Enable or disable multi-factor authentication

Home / Help Center / Microsoft 365 help / Enable or disable multi-factor authentication

Multi-factor authentication (MFA) adds additional security to your Microsoft 365 accounts by preventing unauthorized access to your email.

Required: You need admin permissions to change MFA settings. For more info, see admin roles from Microsoft.

Enable multi-factor authentication

  1. Sign in to Outlook on the web with your Microsoft 365 email address and password.
  2. Once you’re signed in, go to the multi-factor authentication page.
  3. Select the check box next to the user having MFA enabled.
    Check box to left of user email address
  4. The quick steps will display on the right. Select Enable.
    Under quick steps, enable and manage user settings options
  5. In the confirmation window, select enable multi-factor auth, and then close.
  6. Select the check box for the same user. Then under quick steps, select Enforce.
    Under quick steps, Disable, Enforce, and Manage user settings options
  7. Sign in to Outlook on the web using the email account for which MFA was just enforced. You’ll need to enter the phone number you want the verification code sent to, and select Next.

Note: You can also use the Microsoft Authenticator app instead of providing a phone number

8. After you’ve set up MFA, you’ll get an app password for email clients that use basic authentication (like Outlook 2010). Make note of this, and select Done.
