Two-Factor Authentication: Frequently Asked Questions

Why is MSU implementing 2FA?

2FA adds another layer of security when logging in to MSU systems.  The first factor required to login is something you know, i.e. your NetID/NetPassword.  The second factor is something you have, typically your smartphone or tablet.  Therefore, even if a hacker is able to get your NetID/NetPassword, he should not be able to login to your account because he does not have your second factor.

What are my authentication method options in Two-Factor Authenticaiton (2FA)?

There are two options for enrolling in 2FA. The recommended option is to receive a push notification to your mobile device. Note that is not a text, but is generated via the DUO mobile app. The second option is to enter a passcode. There are three methods available to obtain a passcode: 1. Go to 2FA. msstate.edu and click "Generate a Two-Factor Authentication Passcode; 2. Access the DUO mobile app on your device and tap the key icon next to Mississippi State University; and 3. Generate a passcode through a hardware token/fob.

Am I required to use 2FA with every CAS login?

Once you choose the DUO authentication method, check the box next to "Remember me for 24 hours". You will not have to use 2FA for 24 hours in that browser on that computer.

What is a DUO passcode?

A passcode is generated by DUO for authentication. The passcode is used as the 2fa authentication method in specific situations such as:

  • You normally use the Duo mobile app for a “Push” notification to your device but you don’t have your mobile device with you.

  • You don’t have a mobile device and need a hardware token (fob) to generate a passcode.

  • You are at a location where there is no cellular or wireless service to your device, so the “Push” notification will not work.

There are three methods available to obtain a passcode.

  1. Go to 2FA.msstate.edu and click “Generate a Two-Factor Authentication Passcode”. This passcode is valid for 24 hours.

  2. Access the DUO mobile app on your device and tap the key icon next to Mississippi State University.   This passcode is good for one-time use.

  3. Generate a passcode through a hardware token/fob.  This passcode is also good for one-time use. Contact the ITS Help Desk regarding a hardware token.

What is autopush?

If autopush is selected during your set up, you will receive a message on your device with a code automatically during the Central Authentication System (CAS) login. This is not the recommended method of 2FA.

What happens if I do not have my mobile device to login?

Go to 2FA.msstate.edu and click Generate a Two-Factor Authentication passcode which is good for 24 hours.

What if I get a new smartphone or device?

If your phone number has not changed. Go to duo.msstate.edu and click Add/Manage Device. Click “Enter a Passcode”. (See “What is a DUO Passcode?” in the FAQ above to learn how to generate one.)  Click “Device Options”. Then click “Reactivate DUO Mobile”. This will prompt a QR code to scan with the DUO App on your new phone. Tap the “+” button, and scan the QR code.

If you have a new phone number or tablet. Go to duo.msstate.edu and click Add/Manage Device. Click “Enter a Passcode”. (See “What is a DUO Passcode?” in the FAQ above to learn how to generate one.) Click “Add another device”. Follow the steps 7 – 14 above for enrolling in two-factor.

Can I have the DUO mobile app on more than one device?

When enrolling in DUO, you are able to add multiple devices.

Is DUO required for VPN or was.msstate.edu?

DUO is required for both Employee and Departmental login to the VPN and for login to was.msstate.edu.

DUO is not currently required for Student login to the VPN.

I have a mobile device, but my camera is broken. Can I still use my device?

Yes. Instead of activating Duo Mobile by scanning the QR code, click the link “Or, have an activation link emailed to you instead”. You will receive an email that will allow you to proceed.
