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

One Tap sign-up
New users can sign up with just one tap, without being interrupted by a
sign-up screen. Users get a secure, token-based, passwordless account
with your app, protected by their Google Account.

One Tap sign-in
Returning users can sign in to your app with one tap on any device,
whether they use a Google Account or a password.
