MOVE BEYOND PASSWORDS | How Passkeys Change the Way You Secure Your Online Accounts



For years, protecting an online account usually meant

remembering a password.

Then came password managers.

Then two-factor authentication.

Then authenticator apps.

Then security keys.

Now another authentication method is becoming increasingly common:

passkeys.

Passkeys change one of the basic assumptions behind online login.

Instead of asking you to prove who you are by typing a secret that a website stores or verifies, a passkey uses cryptographic credentials associated with your account and your device or credential manager.

You may simply unlock your phone or computer with:

  • A fingerprint
  • Face recognition
  • A device PIN
  • Another supported device-unlock method

and the authentication system handles the cryptographic work behind the scenes.

The result is a login experience that can be easier for users while being resistant to many forms of phishing.

This is not merely another password feature.

It represents a broader change in how digital identity works.

THE CORE PROBLEM WITH PASSWORDS

A password is a secret.

You know it.

You type it.

The website verifies it.

That sounds simple.

But the same characteristic creates several security problems.

A password can be:

  • Guessed
  • Reused
  • Stolen
  • Phished
  • Shared
  • Written down
  • Captured by malware
  • Exposed through a compromised service
  • Accidentally entered into a fake website

The most dangerous part is often not the password itself.

It is the fact that you can be tricked into giving the password to the wrong website.

Imagine receiving a convincing message:

“Your account has a security problem. Sign in immediately.”

You click the link.

The page looks almost identical to the real service.

You enter:

Email
Password

The fake website now has your password.

Traditional password authentication cannot inherently determine whether you voluntarily typed your secret into the legitimate website or into a convincing imitation.

That is one of the problems passkeys are designed to address.

WHAT IS A PASSKEY?

A passkey is a FIDO authentication credential based on public-key cryptography and FIDO standards.

It can be stored on a device, synced through a supported credential manager, or held by a compatible hardware security key. FIDO describes passkeys as credentials that let users authenticate using the same general mechanism used to unlock their device, such as a biometric or PIN.

The important idea is:

Your secret authentication material does not have to be typed into the website.

Instead, the authentication system uses cryptographic keys.

A simplified model looks like this:

YOUR DEVICE
    ↓
PRIVATE KEY
    ↓
PROVES CONTROL
    ↓
WEBSITE
    ↓
PUBLIC KEY
    ↓
VERIFIES PROOF

The private key is not simply sent to the website as a password would be.

That changes the security model.

THE SIMPLE MENTAL MODEL

Think about a traditional password like this:

YOU
 ↓
TYPE SECRET
 ↓
WEBSITE
 ↓
VERIFY SECRET

Now compare it with a passkey:

YOU
 ↓
UNLOCK YOUR DEVICE
 ↓
DEVICE USES PASSKEY
 ↓
CRYPTOGRAPHIC PROOF
 ↓
WEBSITE VERIFIES IT
 ↓
SIGNED IN

You still authenticate.

You simply do not have to manually type a reusable secret into the website.

PUBLIC KEY CRYPTOGRAPHY IS THE FOUNDATION

To understand passkeys properly, you need a basic idea of public-key cryptography.

A cryptographic key pair contains:

PRIVATE KEY
+
PUBLIC KEY

The private key is kept under the control of the authenticator.

The public key can be provided to the service.

Conceptually:

PRIVATE KEY
     │
     │ creates cryptographic proof
     ↓
AUTHENTICATION REQUEST
     │
     ↓
WEBSITE
     │
     │ verifies using public key
     ↓
AUTHENTICATED

The website does not need to know your private key in order to verify that the authentication operation was performed by the holder of the corresponding credential.

That is fundamentally different from a password database containing reusable secrets.

WHAT HAPPENS WHEN YOU CREATE A PASSKEY?

The details vary by platform and service, but conceptually the process looks like this:

YOU CHOOSE
"CREATE PASSKEY"
       ↓
DEVICE / AUTHENTICATOR
GENERATES CRYPTOGRAPHIC CREDENTIAL
       ↓
PRIVATE KEY
REMAINS PROTECTED
       ↓
PUBLIC KEY
IS REGISTERED WITH SERVICE
       ↓
PASSKEY IS READY

The service associates the credential with your account.

Later, when you sign in, the service sends an authentication challenge.

Your authenticator performs the required cryptographic operation.

The service verifies the response.

You are authenticated.

WHY DOES YOUR FINGERPRINT OR FACE UNLOCK THE PASSKEY?

This creates a common misunderstanding.

People sometimes say:

“My fingerprint is my passkey.”

That is not quite right.

Your fingerprint or face is generally used to unlock or authorize use of the credential on your device.

The biometric itself is not simply sent to the website as your password.

Google explains that when its users authenticate with a passkey, biometric information such as a fingerprint or face scan remains on the device and is not shared with Google.

Think of it this way:

FINGERPRINT / FACE / PIN
            ↓
     UNLOCK AUTHENTICATOR
            ↓
       USE PASSKEY
            ↓
   CRYPTOGRAPHIC PROOF
            ↓
          WEBSITE

Your biometric is therefore part of the local authentication process.

WHY PASSKEYS RESIST PHISHING

This is one of their most important properties.

Suppose you visit:

realbank.com

and your passkey is registered for that legitimate service.

A criminal creates:

realbank-security-example.com

and makes it look identical.

With a traditional password, you might be tricked into typing your password into the fake website.

A passkey is tied to the legitimate relying party/domain context.

The cryptographic credential is designed to work with the service for which it was created rather than simply handing a reusable secret to whatever website asks for it.

That is why passkeys are described as phishing-resistant.

FIDO explains that passkeys use cryptographic credentials tied to an account on a website or application rather than requiring the user to enter a password.

PASSWORD VS PASSKEY

Characteristic Password Passkey
User types a secret Usually Usually no
Reusable secret Yes No password secret is typed into the site
Can be phished directly Yes Designed to resist phishing
Can be reused across sites Yes Credentials are tied to services
Cryptographic keys Not inherently Yes
Device unlock can authorize sign-in Not inherently Yes
Recovery still matters Yes Yes
Eliminates every account attack No No

The final row is important.

Passkeys improve authentication security. They do not make an account invincible.

PASSKEYS DO NOT MEAN “NO SECURITY”

The word passwordless can create another misunderstanding.

Passwordless does not mean:

“No authentication is required.”

It means the user does not necessarily authenticate by entering a traditional password.

You still prove control of an authenticator.

For example:

PHONE
 ↓
FINGERPRINT
 ↓
PASSKEY
 ↓
SERVICE

or:

COMPUTER
 ↓
PIN
 ↓
PASSKEY
 ↓
SERVICE

The security mechanism has moved.

WHAT IF SOMEONE STEALS MY PHONE?

This is an important question.

A stolen device does not automatically mean an attacker can use every passkey stored on it.

Modern devices protect authentication credentials using device security mechanisms.

A passkey may require the device to be unlocked before it can be used.

But the broader security of the device matters enormously.

That means:

Your phone's lock screen is now part of your identity-security system.

Protect it accordingly.

Use a strong device PIN or another appropriate secure unlock method.

Do not treat the phone as merely a communication device.

It may contain:

  • Passkeys
  • Passwords
  • Authentication apps
  • Email accounts
  • Banking access
  • Recovery information
  • Personal documents
  • Business accounts

Your device is increasingly an identity-security boundary.

SYNCED VS DEVICE-BOUND PASSKEYS

Not every passkey behaves exactly the same way.

Two important categories are:

Synced passkeys

These can be synchronized across compatible devices through a credential manager or platform ecosystem.

For example:

PHONE
  ↕
CREDENTIAL MANAGER
  ↕
TABLET
  ↕
COMPUTER

This can make recovery and multi-device use easier.

Device-bound passkeys

These remain tied to a particular authenticator or hardware device.

Hardware security keys are an important example.

FIDO distinguishes synced passkeys from device-bound credentials and explains that passkeys can be stored on devices, synchronized through supported systems, or bound to a particular device or security key.

WHICH TYPE SHOULD YOU USE?

There is no single answer for every account.

Consider:

Synced passkeys

Useful when:

  • You use multiple devices
  • Convenience matters
  • You want easier cross-device access
  • Your platform supports reliable credential synchronization

Device-bound credentials

Useful when:

  • You need stronger control over where the credential exists
  • The account is particularly sensitive
  • You are managing high-value organizational access
  • Hardware security keys are appropriate

For extremely sensitive environments, organizations may combine multiple authentication mechanisms and security controls rather than relying on one credential alone.

PASSKEYS AND TWO-STEP VERIFICATION

Passkeys can change how multi-factor authentication works.

A traditional login might be:

PASSWORD
   ↓
SMS CODE
   ↓
ACCESS

or:

PASSWORD
   ↓
AUTHENTICATOR APP
   ↓
ACCESS

A passkey can provide a stronger authentication mechanism without requiring the same password-plus-code workflow.

FIDO explains that passkeys can incorporate possession of the device together with local user verification such as a PIN or biometric, depending on how the credential and service are configured.

However, do not assume that every website implements passkeys identically.

The exact authentication and recovery experience depends on the service.

WHAT HAPPENS TO YOUR PASSWORD?

Creating a passkey does not necessarily delete your password.

Google explicitly states that adding a passkey to a Google Account does not automatically remove the account's existing authentication or recovery factors.

That means you may temporarily have:

PASSWORD
+
PASSKEY
+
RECOVERY METHODS

This can be useful during transition.

But it also means you should understand your account's complete authentication surface.

THE RECOVERY PROBLEM

Here is an important principle:

Authentication is only as strong as the recovery system surrounding it.

Imagine someone has a highly secure passkey.

But the account has a weak recovery process.

An attacker may attempt to bypass the strong primary authentication by attacking recovery instead.

Think of the account as:

             ACCOUNT
                │
      ┌─────────┼─────────┐
      ↓         ↓         ↓
   SIGN-IN   RECOVERY   DEVICES
      │         │         │
      └─────────┼─────────┘
                ↓
           ACCOUNT SECURITY

Therefore, moving to passkeys should not cause you to ignore:

  • Recovery email
  • Recovery phone
  • Backup codes
  • Trusted devices
  • Security keys
  • Account recovery procedures
  • Active sessions
  • Device security

PASSKEYS ARE NOT MAGIC

Passkeys significantly change the authentication problem, but they do not eliminate every threat.

Attackers can still target:

  • Your device
  • Your email
  • Your recovery process
  • Your session
  • Your identity
  • Your support interactions
  • Malware
  • Social engineering
  • Weak account-management procedures

A secure authentication credential is one component of a larger security architecture.

THE ACCOUNT SECURITY STACK

Think of account protection as layers:

DEVICE SECURITY
       ↓
AUTHENTICATION
       ↓
RECOVERY SECURITY
       ↓
SESSION SECURITY
       ↓
APPLICATION SECURITY
       ↓
USER AWARENESS
       ↓
MONITORING

Passkeys primarily strengthen the authentication layer.

They do not replace the others.

PASSKEYS AND PHISHING

Traditional phishing often tries to steal:

USERNAME
+
PASSWORD

More sophisticated attacks may also attempt to capture:

PASSWORD
+
ONE-TIME CODE

Passkeys are designed to make this type of credential theft much harder because the authentication credential is cryptographically bound to the legitimate service.

That is one reason organizations are increasingly moving toward phishing-resistant authentication.

Microsoft announced that Microsoft Entra ID would make passkeys the default authentication experience beginning September 1, 2026, and plans to retire Microsoft-provided SMS and voice authentication in Entra ID from February 1, 2027.

This is an important industry direction:

Authentication is moving away from easily phished shared secrets.

PASSKEYS ARE MOVING INTO THE MAINSTREAM

This is no longer merely an experimental security concept.

The FIDO Alliance reported in May 2026 that an estimated 5 billion passkeys were in active use globally. Its 2026 research surveyed 11,000 consumers across ten countries and reported that 75% had enabled a passkey on at least one account.

The surveyed countries included the United States, United Kingdom, France, Germany, Australia, Singapore, Japan, South Korea, China and India.

That population should not be interpreted as representing every country or every Internet user.

But it demonstrates the scale at which passkeys are being adopted internationally.

WHAT ABOUT NIGERIA AND OTHER DEVELOPING MARKETS?

The basic technology is global.

But practical adoption can depend on:

  • Device compatibility
  • Operating-system version
  • Browser support
  • Account-provider support
  • Access to reliable devices
  • Account recovery options
  • Digital literacy
  • Connectivity
  • Availability of security hardware

This matters because digital security advice should not assume that everyone has the same technology environment.

A strong security system should work within the devices and services people actually use.

HOW TO START USING PASSKEYS

You do not need to convert every account at once.

Start with important accounts that support passkeys.

Consider accounts such as:

  • Primary email
  • Cloud storage
  • Major identity accounts
  • Important developer accounts
  • Business services
  • Financial services where supported
  • Other accounts containing valuable information

Your primary email deserves particular attention.

If an attacker gains control of your main email account, they may be able to target password resets and account recovery for other services.

Think of it as an identity hub.

STEP 1 — SECURE YOUR DEVICE

Before creating passkeys, secure the device itself.

Use:

  • A strong device PIN
  • Biometric protection where appropriate
  • Current operating-system updates
  • Screen-lock protection
  • Appropriate device recovery
  • A secure account associated with the device

Do not create sensitive passkeys on a device that other people regularly use.

Google specifically advises against creating a passkey on a shared device.

STEP 2 — CHECK WHETHER THE ACCOUNT SUPPORTS PASSKEYS

Look in the account's:

  • Security settings
  • Sign-in settings
  • Authentication settings
  • Password settings

You may see:

Passkeys

or:

Create a passkey

or:

Add a passkey

The wording varies by service.

Do not create a passkey through a random link in an email.

Go directly to the legitimate service.

STEP 3 — CREATE THE PASSKEY

The service will normally guide you through the process.

You may be asked to:

  • Confirm your identity
  • Choose where to save the credential
  • Unlock your device
  • Use a fingerprint
  • Use face recognition
  • Enter a PIN
  • Use a security key

Follow the service's instructions carefully.

STEP 4 — VERIFY THAT IT WORKS

Do not simply create the passkey and assume everything is fine.

Test:

  1. Sign out.
  2. Return to the legitimate service.
  3. Choose the passkey sign-in option.
  4. Authenticate.
  5. Confirm that you can access the account.

You should understand the actual experience before relying on the passkey.

STEP 5 — REVIEW RECOVERY

After setting up the passkey, inspect:

  • Recovery email
  • Recovery phone
  • Backup codes
  • Security keys
  • Trusted devices
  • Active sessions
  • Other authentication methods

Your objective is not simply:

“I created a passkey.”

Your objective is:

“I understand how I will regain access if something happens to my device.”

GOOGLE ACCOUNT EXAMPLE

Google currently supports passkeys for Google Accounts.

Google says passkeys can be used with a fingerprint, face scan, device screen lock such as a PIN, or a compatible security key. Google also notes that passkeys do not automatically remove existing authentication or recovery factors.

Google also offers Advanced Protection for users at elevated risk of targeted attacks, using security keys or passkeys as part of its stronger authentication requirements.

The important lesson is not simply:

“Use Google passkeys.”

It is:

Learn how the specific service implements passkeys and recovery before changing your authentication setup.

MICROSOFT ACCOUNT EXAMPLE

Microsoft supports passkeys for personal and work/school accounts.

Its current support documentation explains that passkeys can be stored in supported password managers or on devices such as Android phones, iPhones/iPads, and Windows devices, depending on the setup.

Microsoft's enterprise authentication strategy is also shifting toward passkeys. Beginning September 1, 2026, Microsoft Entra ID is scheduled to make passkeys the default authentication experience for users affected by the transition from SMS or voice authentication.

This illustrates an important trend:

Passkeys are moving from an optional security feature toward a mainstream authentication method.

DO NOT DELETE EVERY OTHER SECURITY METHOD IMMEDIATELY

This deserves emphasis.

After creating a passkey, do not immediately remove every other authentication and recovery method without understanding the consequences.

First confirm:

  • The passkey works
  • You know where it is stored
  • You have a recovery path
  • You understand your account's security settings
  • You have access to backup methods where appropriate

Security changes should reduce risk, not create a new lockout problem.

THE DEVICE BECOMES MORE IMPORTANT

As authentication becomes increasingly device-based, protecting your devices becomes more important.

Think about your phone:

PHONE
 ├── Passkeys
 ├── Password manager
 ├── Email
 ├── Banking
 ├── Authentication apps
 ├── Recovery codes
 ├── Business accounts
 └── Personal data

This means:

Device security is now identity security.

A strong device PIN and appropriate device protection are no longer minor conveniences.

They are part of your digital security architecture.

TRY THIS: AUDIT YOUR TOP 10 ACCOUNTS

Make a list of your ten most important online accounts.

For each one, record:

Account Password MFA Passkey Recovery Importance
Primary email ✓ ✓ ? ✓ Critical
Cloud storage ✓ ✓ ? ✓ High
Business account ✓ ? ? ? High
Developer account ✓ ✓ ? ✓ High
Financial account ✓ ✓ ? ✓ Critical

Do not copy passwords into a spreadsheet.

The table is for security-method inventory, not secret storage.

Then identify which important accounts support passkeys.

SOLVE THIS: WHICH ACCOUNT SHOULD YOU PROTECT FIRST?

Suppose you have:

  • A social-media account
  • An online shopping account
  • A primary email account
  • A cloud storage account
  • A developer account

Which should receive the most attention first?

Don't simply ask:

“Which account is most valuable?”

Ask:

“Which account could provide access to other accounts or valuable information if compromised?”

Your primary email may have enormous importance because it can participate in account recovery.

Your cloud storage may contain personal or business documents.

A developer account may control valuable code or infrastructure.

The right priority depends on what each account controls.

This is risk-based security.

COMMON PASSKEY MISTAKES

1. Creating a passkey on a shared device

A shared device can create account-access problems.

2. Forgetting recovery

A secure login method is not useful if you have no safe way to recover the account.

3. Assuming passkeys protect everything

They primarily improve authentication.

Your device, sessions, recovery mechanisms and applications still require protection.

4. Treating biometrics as the passkey

The biometric normally authorizes local use of the credential.

It is not simply transmitted to the website as your authentication secret.

5. Creating credentials through suspicious links

Go directly to the legitimate service.

6. Ignoring account inventory

You need to know which accounts have which authentication methods.

7. Removing existing security methods too quickly

Verify the new system first.

8. Ignoring device security

A passkey on an inadequately protected device is part of an inadequately protected identity system.

9. Believing passkeys eliminate social engineering

Attackers can still manipulate people through support scams, fake recovery processes and other methods.

10. Assuming every service works the same way

Implementation, synchronization, recovery and authentication options vary between services.

WHEN A PASSWORD STILL EXISTS

Passkeys do not mean the entire Internet has suddenly eliminated passwords.

Many services still use passwords.

Some support:

PASSWORD
+
MFA

Some support:

PASSWORD
+
PASSKEY

Some support:

PASSKEY

Some support security keys.

The Internet is therefore in a transition period.

You may need to manage different authentication systems for years.

That is normal.

PASSWORD MANAGERS STILL MATTER

Passkeys do not make password managers obsolete.

Passwords are still widely used.

A password manager can help you:

  • Generate unique passwords
  • Store passwords securely
  • Avoid password reuse
  • Fill credentials
  • Manage legacy accounts
  • Store secure notes
  • Help transition gradually toward passkeys

A sensible long-term model may therefore be:

PASSKEYS
     +
PASSWORD MANAGER
     +
MFA WHERE APPROPRIATE
     +
SECURE RECOVERY
     +
DEVICE SECURITY

The objective is not to follow a fashionable authentication trend.

The objective is to reduce avoidable account risk.

THE FUTURE OF LOGIN

Traditional authentication has often looked like:

USERNAME
    +
PASSWORD
    +
SECOND FACTOR

The direction of travel is increasingly:

DEVICE
   +
CRYPTOGRAPHIC CREDENTIAL
   +
LOCAL USER VERIFICATION
   +
SECURE RECOVERY

This can create a login experience that is simultaneously easier for users and more resistant to common credential attacks.

But the transition will not happen identically everywhere.

Legacy systems, organizational requirements, recovery mechanisms, device ecosystems and compatibility all matter.

A BIGGER DIGITAL IDENTITY LESSON

Passkeys teach a much bigger lesson about the Internet.

For years, many users thought of identity as:

“My username and password.”

That model is becoming incomplete.

Modern digital identity increasingly involves:

  • Devices
  • Cryptographic credentials
  • Biometrics
  • Security keys
  • Account recovery
  • Sessions
  • Identity providers
  • Authentication policies
  • Authorization
  • Digital credentials

The password was only one piece of the identity puzzle.

Passkeys make that more obvious.

PASSKEYS AND THE FUTURE OF DIGITAL TRUST

As more services move toward phishing-resistant authentication, the concept of digital trust changes.

A secure website is not only about HTTPS.

A secure account is not only about a strong password.

A trustworthy digital system increasingly depends on:

SECURE DEVICE
      ↓
STRONG IDENTITY
      ↓
PHISHING-RESISTANT AUTHENTICATION
      ↓
SECURE RECOVERY
      ↓
APPROPRIATE AUTHORIZATION
      ↓
MONITORING
      ↓
RESPONSIBLE USER

This is the direction in which digital security is evolving.

AN IMPORTANT WARNING FROM CURRENT RESEARCH

Passkeys are not automatically implemented perfectly everywhere.

A 2026 USENIX Security study examined passkey deployments across hundreds of websites and found substantial differences in how sites implemented and managed passkeys. The researchers also identified vulnerabilities in some implementations, including issues that could allow account takeover or lock users out.

This produces an important professional lesson:

A strong security standard does not guarantee that every implementation is equally secure.

Security depends on:

  • The standard
  • The implementation
  • The surrounding application
  • Credential management
  • Recovery
  • Session handling
  • User interface
  • Operational practices

So passkeys are a major security improvement, but they should still be evaluated as part of the complete system.

THE W3 NOTES ACCOUNT SECURITY MODEL

A practical W3 NOTES model is:

1. SECURE THE DEVICE
        ↓
2. USE UNIQUE CREDENTIALS
        ↓
3. PREFER PHISHING-RESISTANT AUTHENTICATION
        ↓
4. USE PASSKEYS WHERE APPROPRIATE
        ↓
5. PROTECT RECOVERY
        ↓
6. REVIEW ACTIVE SESSIONS
        ↓
7. KEEP SOFTWARE UPDATED
        ↓
8. MONITOR IMPORTANT ACCOUNTS
        ↓
9. RESPOND QUICKLY TO SECURITY ALERTS
        ↓
10. REVIEW THE SYSTEM PERIODICALLY

Notice that passkeys are one part of the system.

That is the correct way to think about cybersecurity.

YOUR PASSKEY MIGRATION CHECKLIST

Use this checklist when moving important accounts toward passkeys.

BEFORE

  • [ ] Device is secured
  • [ ] Device software is current
  • [ ] Account recovery is understood
  • [ ] Existing MFA is understood
  • [ ] You know where the passkey will be stored

DURING

  • [ ] You are on the legitimate website/app
  • [ ] You create the passkey through the account's security settings
  • [ ] You understand where it is saved
  • [ ] You complete the required device verification

AFTER

  • [ ] Test passkey sign-in
  • [ ] Review recovery methods
  • [ ] Review active sessions
  • [ ] Confirm other trusted devices
  • [ ] Record the account's security configuration
  • [ ] Do not store secrets in an insecure document

THE BIG IDEA

Passwords are not disappearing overnight.

But the Internet is moving toward a different authentication model.

Instead of repeatedly asking users to prove their identity by revealing reusable secrets, modern authentication can use cryptographic credentials that prove control without exposing the credential itself to the website.

That is the fundamental idea behind passkeys.

The important shift is:

FROM

"KNOW A SECRET"
       ↓
PASSWORD
       ↓
VERIFY PASSWORD


TO

"CONTROL A CREDENTIAL"
       ↓
PASSKEY
       ↓
PROVE CONTROL CRYPTOGRAPHICALLY

The technology underneath is sophisticated.

The user experience can be remarkably simple.

You unlock your device.

The device helps authenticate you.

You continue.

That combination—stronger cryptography with simpler human interaction—is one of the most important directions in modern digital identity.

YOUR NEXT STEP

Do not try to redesign your entire digital security system today.

Start with your most important account.

Check whether it supports passkeys.

Then ask four questions:

  1. Can I create a passkey?
  2. Where will it be stored?
  3. How will I recover the account if my device is lost?
  4. What other authentication and recovery methods remain active?

Once you understand those four answers, move to the next important account.

The goal is not simply to collect passkeys.

The goal is to build an authentication system that is harder to phish, easier to use, recoverable when things go wrong, and appropriate for the value of what you are protecting.

KNOWLEDGE MAP

Passkeys connect several important areas of the digital world:

PASSWORDS
    ↓
MULTI-FACTOR AUTHENTICATION
    ↓
PUBLIC-KEY CRYPTOGRAPHY
    ↓
FIDO2 / WEBAUTHN
    ↓
PASSKEYS
    ↓
DIGITAL IDENTITY
    ↓
PHISHING-RESISTANT AUTHENTICATION
    ↓
SECURE RECOVERY
    ↓
DIGITAL TRUST

And that leads to a much bigger understanding:

Your online identity is no longer just a username and password. It is a system of devices, credentials, authentication methods, recovery mechanisms, permissions and trust relationships.

Learning how that system works is one of the most practical cybersecurity skills an Internet user can develop.
