Based on industry standards for account authentication, passkeys are easier to use than passwords and far more secure. In the Safari app with iOS16, you can use Face ID or Touch ID to securely sign in to supporting websites. This works for sites that require log-in credentials. Passkeys on iPhone require that you use iCloud Keychain. If you don’t have iCloud Keychain turned on when you try to save a passkey, you’ll be asked to turn it on.
How to save a passkey
For a new account: On the account sign-up screen, enter an account name
For an existing account: Sign in with your password, then go to the account management screen
When you see the option to save a passkey for the account, tap Continue
Your passkey is saved
If you want to save your credentials to an external security key or to a different device not associated with your Apple ID, you may be able to select Other Options, Save on Another Device, or similar (instead of Continue). Then follow the onscreen instructions.
