Changing your default MFA authentication method

Learn how to change your default authentication method with Azure MFA. You can authenticate via the Microsoft Authenticator app on a smartphone, use a passkey, or another phishing-resistant method.

Description

You can multi-factor authenticate (MFA) through the Microsoft Authenticator app, a phone call, a text message, or a hardware token. The Authenticator app is the recommended authentication method. 

Important: Microsoft-provided SMS text message and phone-call authentication methods will no longer be supported beginning February 1, 2027.

  • App based authentication - notification

    • Use the Microsoft Authenticator app on your phone/tablet to authenticate. 

    • This is the most secure way to authenticate.

    • App notifications work over both Wi-Fi and cellular networks. 

    • You can also use a one-time password code in the Authenticator app if your phone cannot connect to a network. 

  • Passkeys

    • Passkeys are a phishing-resistant authentication method that allows you to verify your identity using a device you already trust, such as your smartphone, tablet, or computer.

    • Sign in using your device's fingerprint, facial recognition, PIN, or screen lock.Faster and more convenient than entering verification codes.

    • Designed to provide stronger protection against phishing and account compromise.

    • Can be used across compatible devices and browsers.

  • App based authentication or hardware token - code

    • Only select this option if you are using a hardware token. A hardware token is a physical device that you can use to authenticate if you do not have a smartphone. View Azure Multi-Factor token request for instructions on requesting a token.

    • Note - You cannot connect to campus VPN with this method. 

• Select Confirm. 

Outcome: You have changed your default MFA method.
