Microsoft is making changes to how users authenticate their Durham College (DC) Microsoft accounts. Beginning February 1, 2027, SMS text messages and phone calls will no longer be available as Microsoft authentication methods.
This change will affect anyone with a DC network account who uses Microsoft services, including DC email, Microsoft Teams, OneDrive and DC Connect.
Why is this changing?
Microsoft is retiring SMS and voice authentication in favour of the Microsoft Authenticator app, which provides a more secure way to verify identity when accessing DC services.
What do I need to do?
If you are already using the Microsoft Authenticator for multi-factor authentication (MFA), no action is required.
Starting September 1, Microsoft will begin prompting users who currently rely on SMS or voice authentication to update their authentication method when signing in. To avoid interruptions when signing in to DC services, these users should set up the Microsoft Authenticator app before February 1, 2027,
What if I don’t have or don’t want to use a mobile device?
A physical security key, such as a YubiKey, can be used as an alternative authentication method. YubiKeys are available for purchase through DC Campus Stores.
Important dates
- September 1, 2026: Microsoft begins prompting users to register a stronger authentication method.
- February 1, 2027: Microsoft-provided SMS and voice authentication will no longer be available. An updated authentication method will be required to avoid interruptions when signing in to DC services.
If you experience difficulties setting up Microsoft Authenticator or another approved authentication method, contact the IT Service Desk.
