Automatically Clean up One-Time Passcodes
Along with the ability to autofill verification codes from Apple Mail, you’ll also be able to prevent those one-time passcodes from cluttering up your Messages list and e-mail inbox.
A prompt to turn this will appear the first time you receive a code after updating to iOS 17, and the option to toggle this on or off can be found in the Passwords section of the iPhone Settings app. The same feature will also be available in macOS Sonoma and iPadOS 17, so if you’re syncing your text messages between devices, they’ll get cleaned up no matter where you use them.
