What exactly is one tap signup?
With one tap signup, users are prompted to create an account with a dialog that’s inline with your page’s content, so they’re never taken out of context by a signup page. Since there’s minimal friction, users are much more likely to register.
Returning users are signed in automatically, even when they switch devices or platforms, or even after their session expires. The existing users with password-based accounts can also sign-in automatically if they’ve saved their password on Chrome or Smart Lock for Passwords on Android.
