Set up your Microsoft 365 sign-in for multi-factor authentication

Office for business Microsoft 365 admin

For multi-factor authentication (MFA) you have to set up your user account to use it. This should only take a minute or so.

By setting up MFA, you add an extra layer of security to your Microsoft 365 account sign-in. Sign in using your college username and password like you normally do. After you choose Sign in, you’ll be prompted for more information.

1. Choose Next.
2. The default authentication method is to use the free Microsoft Authenticator app. Please see further guidance on how to use the App below. If you have it installed the app, select Next and follow the prompts to add this account. If you don’t have it installed there is a link provided to download it.
3. If you would rather use SMS messages sent to your phone instead, select I want to set up a different method. Microsoft 365 will ask for your mobile number, then send you an SMS message containing a 6-digit code to verify your device.
4. Once you complete the instructions to specify your additional verification method, the next time you sign in to Microsoft 365, you’ll be prompted to provide the additional verification information or action, such as typing the verification code provided by your app or sent to you by text message.
