Starting Q1 2024 as part of Chrome-facilitated testing, 1% of Chrome
Stable users disable third-party cookies. To prevent breaking Google Sign-In
for users, this library is part of Chrome's Privacy Sandbox
deprecation trial. For the duration of the trial use of this library is
not affected by the rollout of third-party cookie blocking.
Support for the Google Sign-in JavaScript library is deprecated as of
March 31, 2023.
New OAuth Client IDs cannot use the deprecated library.
Existing Client IDs created before July 29th, 2022 may set
plugin_name to continue using the library.
Sunset (shutdown) date of the deprecated library is yet to be determined.
We'll send out advanced notices to affected developers when sunset date is
confirmed. Make sure your Google Cloud Platform Project contact
information associated with your OAuth client ID(s) is correct.
We'll also announce the sunset date here. Bookmark this page and come back
often for updates.
For detailed instructions on how to migrate your web app from the deprecated
Google Sign-In JavaScript library to the Google Identity Services library,

Definition
The deprecated library is a version that is not the latest one.
The sunset library can no longer be used. Requests sent to this
library will fail on or after the sunset date.
Implication
For existing OAuth client ID(s) using the deprecated library, you can still
use the deprecated library until they're sunset,
but any new OAuth client ID cannot use the deprecated library.
Migrate to the Google Identity Services library as soon as possible to
benefit from new features.
You need to migrate off the sunset library immediately in
order to use Google services.
