One Tap is our new cross-platform sign-in mechanism for Web and Android, supporting and streamlining multiple types of credentials.

Seamless sign-in and sign-up flows

Sign up new users with just one tap, without interrupting them with a sign-up screen. Users get a secure, token-based, passwordless account on your site, protected by their Google Account.
Sign in users automatically when they return to your site on any device or browser, even after their session expires.
