Google adds notification for two-stage authentication to Gmail for iOS
Google adds the notification asking if users are trying to sign in to Gmail for iOS on another device. The window has so far only appeared in the Google app for iOS, but it’s probably on fewer iPhones and iPads.
Two-step authentication ensures that user accounts are less easy to take over. Less than 10 percent of Gmail users had the extra form of security in January. In addition to the window, users can also choose other ways of logging in with a second factor, such as the Google Authenticator app for iOS and Android.
