M365 Changelog: Update to the OAuth 2.0 device authorization grant flow protocol

MC260483 – As a security improvement, the device code flow has been updated to include an additional prompt when a user signs into an app. The addition of this prompt is to confirm that the user is signing into the app in which they intend to, to help prevent phishing attacks.

How does this affect me?
Starting June 2021, users will see this prompt when signing in using the device code flow. As a security measure, it cannot be removed or bypassed. You can view this article for more information.

Please contact Microsoft Support if you have any questions.
