Texas A&M and Two-Factor Authentication: The Perfect Duo

Duo adds an extra layer of security to Texas A&M NetID accounts. With Duo two-factor authentication, NetID accounts are protected with something you know (a password) and something you have (a Duo-enrolled device - typically a mobile phone).

The Duo Mobile App is easy to use and set up. No mobile phone? Other options are available. Review our Duo FAQs and Guide to Two-Factor Authentication to help make the best choice.

Pro Tip: Be sure to set up more than one device with Duo! If you leave your phone at home or the battery dies, you can use your secondary device as a backup.

Frequently Asked Questions

What if I leave my phone at home, the battery dies or I lose it?

Hopefully you followed our tip and set up a secondary device. If so, log in to gateway.tamu.edu and in the main screen select “set up my Duo Two Factor Authentication.”

Once there, use the dropdown to select your backup device. If it is a tablet, you can have it send you a push. If it’s a landline, you can have it call you. Crisis averted. Just be sure to change the device once you can access your phone.

If you didn’t set up a secondary device, call Help Desk Central at helpdesk@tamu.edu or 979.845.8300 and they can assist with a one-time code.
