In May 2016, we released the newest version of Google Identity Toolkit as Firebase Authentication, and in April 2019, we released Google Cloud's Identity Platform. These products include upgraded client SDKs, open source UI libraries, session management and integrated email sending service for forgotten password flows.

On June 30, 2020, the SDKs documented on this page and the API setting page will stop functioning. (The https://identitytoolkit.googleapis.com/... and https://securetoken.googleapis.com/... endpoints, used by Identity Platform and Firebase Authentication, will continue to function.)

To migrate an existing project from Identity Toolkit, see the Identity Platform migration guide or Firebase Authentication migration guide.

Identity Toolkit UX

Out of the box, Google Identity Toolkit provides a fully functioning login flow, designed to get users into your site as quickly and easily as possible. Check out our password-only or federated login demo sites to see it in action.

The design embodies the very latest of our user experience research. If you have any questions or concerns about our features, we ask that you first check out our documents on the Account Chooser and the step-by-step description of our login flow.

Still have concerns? Post your question on our forum and we'll get back to you as soon as possible.
