Google Drive: Migrate OAuth out-of-band flow to an alternative method
Starting October 3, 2022, Google will block OOB requests to Google’s OAuth 2.0 authorization endpoint for existing clients. A request for a one-time extension for migrating our app until January 31, 2023 was sent to Google today. All OOB authorization requests will be blocked on February 1, 2023.
A more secure OAuth interaction way will need to implemented. For details, see https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html
