Summary:
Microsoft Teams is updating authentication for Android-based Teams devices to enhance security. Organizations managing these devices must update to specified app versions by December 31, 2025, to avoid service disruption. Key dates include July 31, 2025, and September 30, 2025, for transitioning to modern authentication.

Details:
If your organization does not manage one or more certified Microsoft Teams Android devices, you can safely ignore this message.
Your organization manages one or more certified Microsoft Teams Android devices, such as Teams Phone devices, Teams Panels, Teams Displays, and Teams Rooms on Android (MTRA). To enhance security capabilities such as Continuous Access Evaluation and IP-based conditional access enforcement, Microsoft is transitioning these devices to modern, secure authentication using Entra ID (AAD) based tokens.
These changes will impact how devices authenticate to Teams services. This update provides key dates, required versions, and important cautions-especially for tenants using Teams Displays.
