This new authentication method must be supported by third-party websites and applications to work.

If a specific website has been updated for Passkeys, you will be able to set one up in the Settings section of your Account on that specific website.

For example, one of the early adopters is BestBuy.com. If you have an account with them, log in the usual way, using the strong password generated by your iPhone when you initially set up your account.

On the BBuy website, go to Settings -> All Accounts Settings -> Face or fingerprint login -> Set up on this device

First users supporting passkeys on iPhone

While testing Passkeys in iOS 16, we had success using this new feature with accounts on the following websites:

  • AOL (only works if you remove the App Authenticator if you have one configured)
  • Best Buy (works as primary authentication)
  • drop box
  • Facebook
  • GithubGenericName
  • come on daddy
  • Google (passkeys may conflict if you have multiple Google accounts for which you have saved the private keys)
  • Twitter
  • WordPress
  • Yahoo (only works if you remove the app authenticator)

Passkeys vs Passwords

You could say that logging in with a password works the same way as authenticating with strong passwords, using iCloud Keychain and Face ID.

In both cases, you choose an identifier among those available, authenticate yourself with biometrics and log in.

However, that’s very the end of the similarities:

  • Signing in with iCloud Keychain automatically fills in your saved username and password into the normal text fields required by a sign-in form.
  • Access keys do much more. iOS 16 generates a unique key accessible only when the user authenticates with biometrics. This makes security keys much more secure as they are stored in iCloud Keychain and not visible to the user.
