Two-factor authentication requires something you know (your NetID password) and something you have (like a mobile phone, landline phone or a smartphone app) as an added layer of security to prevent anyone else from accessing your account. Two-factor authentication is the most effective method of account takeover prevention, helping to protect both you and the AU community.


Passwords are essential for security and privacy, but they are often not enough. They can be stolen, guessed, or hacked.  You might not even know who else has your password and is accessing your account. Two-factor authentication adds a second layer of security to your account to make sure that it stays safe, even if someone else knows your password, by using your phone or other device to verify your identity. You will be alerted right away (on your phone - mobile or landline - or tablet) if someone tries to log in using your password. This prevents anyone but you from accessing your accounts.


Duo's self-enrollment process makes it easy to register your phone or tablet and install the application on your device. You can complete your enrollment by following the instructions here. After completing the process, you can test the authentication process by logging out and logging back into


When setting up DUO we recommend utilizing the Duo Push authentication method. To know why please review our DUO FAQs. If you are unable to download Duo Push there are other options that may work for you.
