How to Set Up Automatic Deletion of Verification Codes from Mail and Messages in iOS 17

The ultimate lifesaver for anyone using two-factor authentication.

Alongside the "Waiting" mode and contact posters in iOS 17, there are many subtle yet equally useful new features. One of these is the automatic deletion of verification codes that websites and services send you via email or SMS when you log into your account.

Now iOS automatically recognizes and inserts one-time passwords not only from "Messages" but also from "Mail." Moreover, after entry, they can also be automatically deleted.

Theoretically, when you first receive and use any verification code after updating to iOS 17, the system should prompt you to activate the automatic clearing feature.

If this did not happen for some reason or you accidentally declined, you can go to "Settings" at any time and open the "Passwords" section.

Confirm your identity using Face ID or your PIN code, then go to "Password Options" and toggle on the "Automatic Clearing" switch. That's it. Now, after pasting, all one-time passwords will be deleted automatically.

The security of enabling this feature will not be affected in any way, as the codes become invalid immediately after use, and even if someone sees them, they still won't be able to apply them. However, this kind of clearing will help keep your inbox uncluttered, which is especially relevant, if you actively use two-factor authentication.
