Discontinuing Google Sign-In JavaScript Platform Library for web

Google announced the deprecation of the JavaScript-based Google Platform Library for web apps, set to be fully retired on March 31, 2023, as part of an effort to enhance user security and streamline sign-in methods. This change affects web apps that use the Google Sign-In JavaScript library, requiring them to migrate to the new Sign In With Google client library, which consolidates multiple identity offerings under Google Identity Services. The migration encompasses both authentication and authorization flows, and it does not impact Android or iOS native app SDKs or services directly calling Google's OAuth2 or OpenID. The new JavaScript library aims to provide a consistent, secure, and low-friction user sign-in experience, improving visibility and trust. Users and developers are encouraged to visit Google's developer site and use community resources like Stack Overflow for assistance, as well as to provide feedback via email.
