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 and 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.
