Apple added Password Authenticator functions in iOS 15 to support cloud synchronization
In the case of frequent leaks of various website databases and the pursuit of more reliable security verification, most network platforms currently support the use of multi-factor verification.
For example, after entering the account and password, you also need to enter a time-based one-time verification code. This verification code can ensure that although the password is leaked, hackers cannot log in.
The most typical and most used one that supports the generation of one-time verification codes should be Google Authenticator. Users need to obtain the latest verification code every time they log in.
But obviously, it is troublesome for users to open the authenticator to obtain the verification code every time they log in, so Apple added an authenticator to the iOS 15 password manager.
The password manager function provided by Apple has been used by many users, and the account password will be automatically saved to the Apple password manager when logging in to the new website.
The next time you log in, you can directly use fingerprints or facial recognition and then auto-fill, so as to avoid the dilemma that users need to enter a password every time they log in to their account.
Under the premise of multi-factor authentication, even if the account password can be automatically filled in, you still have to go to the verifier to obtain the verification code, and then return to the page to paste it.
This process can improve security but also makes it inconvenient for users to use, so Apple has brought an authenticator function to the iOS 15 password manager.
When the user is bound to the two-step verification, the dynamic verification code can also be automatically pasted when logging in next time, and the user only needs to perform fingerprint or facial recognition to confirm.
Generate verification codes needed for additional sign-in security. If a site offers two-factor authentication, you can set up verification codes under Passwords in Settings — no need to download an additional app. Once set up, verification codes autofill when you sign in to the site.
