Signing in to Microsoft applications and services has different steps than other Princeton applications though it still requires Duo two-factor authentication.

The experience may also differ depending on whether Microsoft Authenticator has been setup as a sign in method for your Princeton University Microsoft account.

Step 1: The Microsoft sign-in page

Enter your netid@princeton.edu.

 

Step 2: Enter password in Microsoft sign-in page

The Microsoft sign-in page detects your Princeton netID and reacts by giving you the appropriate Princeton authentication experience.

Enter your password in the Microsoft sign-in page, as shown below:

Step 3: Two-factor Authentication with Duo

Assuming you entered a valid password, you’ll be asked to Verify your identity. Note that this screen includes the Princeton logo at the top and the Princeton-specific help text at the bottom.

You should see Approve with Duo Two-Factor Authentication as shown.

 

Once you have chosen Approve with Duo Two-Factor Authentication, you will be directed to a Duo verification page to complete your authentication and sign in.

If you previously set up Microsoft Authenticator as a sign-in option for your Princeton Microsoft account, you may see a different option.

Two-factor authentication with Microsoft Authenticator

If you see either of the screens below instead of the Duo option to Verify your identity, you may have Microsoft Authenticator set up as a sign-in option.

On either screen you have the option to select I want to use a different authenticator app or Sign in another way and follow the prompts for Duo Two-Factor Authentication. 

Unless Microsoft Authenticator is deleted as a sign-in method for your Princeton Microsoft account, you may continue to receive this prompt for authentication when signing in to Microsoft applications and services.

If you're unable to complete the two-factor authentication step, contact the IT Service Desk.
