Authenticate Apps with Ease
Many apps and sites now support 2FA (two-factor authentication) which verifies your identity when you log in by sending you a code. Usually this can be sent via phone or email, but it can also come from an authenticator app.
Apple has made 2FA codes easy by allowing you to autofill codes from text messages. Now, you can set up authenticator codes using iOS too.
When setting up an authenticator for a service you’ll be asked to scan a QR code (using the Camera app) and/or be provided with a setup key.
Copy this key and open the Settings app.
Navigate to the passwords section and select the entry from the list (or create a new one).
Now select “Set Up Verification Code.”
Here you’ll paste the key and Apple will begin providing you with a six-digit code used for verification.
Some sites will allow this to autofill this code when logging in. Keep in mind, it’s still pretty new, so in some cases, you will need to go into Settings > Passwords and copy the code manually.
