Recommendation, for better security and most convenient use, select the Mobile app along with Receive notifications for verification selected. Once these options are selected, click Set up and a new window with a QR code will appear. Have your phone in hand and proceed to Step 4 for QR code scanning.
4. On your new phone, open the Microsoft Authenticator app that you downloaded in Step 1, click Add Account and click OK allow camera access (Pic 1 & 2), then select Work or School Account and select Scan QR code (Pic 3).

When successful, the QR scan box will turn green and your TSU account will be added to your phone.
5. Success! You have officially registered your new phone and MyTSU account for Multi-Factor authentication. Make sure to Allow notifications for the MS Authenticator. Your phone should now display your TSU email address on your MS authenticator app. You can close the app on your phone. On your PC, click Next on the Configure Mobile App window. You will return to the Additional Verification Screen.
6. On your PC, you will see the Setup button greyed out, indicating successful setup of your mobile app. Click Next on the Additional Security Verification Screen. On the Additional Security Verification Screen (Pic 1), it will test that your phone synched with your TSU MFA account by asking you to Approve your attempted sign-in request on your phone (Pic 2). Click Done on the Additional Security Verification Screen. MFA on your PC (Pic 3) will ask you to Approve another sign-in on your phone.
7. On Your PC, you will see 2 devices listed under the Authenticator app section. They are listed in order from NEWEST to OLDEST. To delete the old device, click DELETE next to the second selection. Once completed, click Cancel located at the bottom of the Additional Security Verification screen (Pic 1) which confirms the settings of your MFA method. You will be redirected to your MFA profile (Pic 2). You can close the current window or open an Internet browser window and successfully go to your MyTSU dashboard (Pic 3).
- MFA Authentication Process: Every time you are on or off campus or connected to the wireless network, please be mindful to have your phone available so that you can login to your MyTSU account and other TSU services. When you attempt to authenticate and successfully enter your MyTSU password, you will receive a Microsoft Authenticator notification (see below) on the home screen of your phone within the MS Authenticator app. Click the notification and then click Approve. If you receive a notification to sign-in and it is NOT you, Click Deny. If you have any issues, please contact the Help Desk 615-963-7777 or helpdesk@tnstate.edu.
