Microsoft Authenticator

When you sign in to a Microsoft 365 service on your computer, such as your Colby-Sawyer College Outlook email, you’ll be prompted to set up multifactor authentication (MFA).

When prompted, select Next.

On your mobile device, download the Microsoft Authenticator app from your mobile device's app store. 

After you install the app, return to your computer and select Next. 

Microsoft will display a QR code on your computer. Leave this QR code page open while you complete the next steps on your mobile device. 

Open the Microsoft Authenticator app on your mobile device. 

Select Add Account or the + icon in the upper-right corner. 

If the app asks you to authenticate with an existing account before adding your Colby-Sawyer account, complete that authentication first. 

Select Work or school account. 

Select Scan QR code, then use your phone to scan the QR code displayed on your computer. 

Return to your computer and select Next. 

Microsoft will send a test notification to the Authenticator app. Open the notification and select Approve. 

Once the test is approved, Microsoft Authenticator will be registered as your MFA method and can be used to approve future sign-ins. 

If you’d like to check your Colby-Sawyer College email on your phone, download the Microsoft Outlook app from your mobile device's app store.
