The beta test program for this API is currently closed. We are improving the API's cross-browser functionality and will provide updates here in the coming months.

Seamless sign-in and sign-up flows

One-tap sign-up

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.

Automatic sign-in

Sign in users automatically when they return to your site on any device or browser, even after their session expires.
