More About Duo Multi-factor Authentication

How It Works

Two steps are required for successful access:

  • Something you know (NetID and password)
  • Something you have (mobile device, landline phone, or key fob)

Duo Mobile preferred method for logging in

With Duo Mobile, quickly approve a Duo request by tapping one button on your mobile device. Duo Mobile can also generate time-based one-time (TOTP) passcodes that users can type into their login prompt to complete the two-factor authentication process.

Passphrases + Duo 

In 2019, Texas State implemented a 15-character minimum on new and reset passwords. The university recommends that you use a passphrase, which is a string of random, familiar words. Research shows a 15-character passphrase is easier for people to remember and harder for criminals and computers to crack. 

Once you are enrolled in Duo and have a 15-character passphrase, you will never need to change your passphrase again!  

You don’t have to wait. Act now to reap this benefit.  

  1. Students: Enroll in Duo and set a 15-character passphrase. If you already have a 15-character passphrase, you need only to enroll in Duo. 
  1. Faculty and Staff: Set a 15-character passphrase. If you already have a 15-character passphrase, you do not need to take any further action. 
  1. Any phrase will do if it is at least 15 characters.
