Multi-Factor Authentication – Setup and Configure
Multi-Factor Authentication is a more secure method of signing-in to systems and resources. It uses multiple “factors” to verify user identity.
At DMU we utilize a Knowledge factor (password) and a Possession factor (mobile device).
To ensure you can always access your Microsoft account, ITS strongly recommends configuring both the Microsoft Authenticator app and a phone number as your sign‑in methods.
When a mobile device is replaced, reset, or restored from backup, the Microsoft Authenticator app may lose its trusted relationship with your account. This can cause authentication failures and prevent you from signing in.
Having a phone number registered as an additional authentication method ensures you can still verify your identity and regain access to your account even if the app becomes unavailable.
Recommended setup:
- Microsoft Authenticator app (primary)
- Phone number for SMS or voice call (backup)
This dual setup provides a reliable fallback and helps avoid account lockouts when changing or replacing devices.
