Duo Two Factor Authentication Portal
Why are we moving to Two Factor Authentication?
Two factor authentication (2FA) is the most effective way to secure our computer accounts and it is easy to use! If you've ever received a text message to confirm your identity when you log into an online retailer or banking site, you've used 2FA. It allows you to confirm your identity by text message, phone call, mobile application, and other methods.
Who is protected with Duo (Two Factor Authentication - 2FA)?
All active UHD network accounts, including admitted students and alumni, are Duo protected.
What is Duo (Two Factor Authentication - 2FA)?
Two Factor Authentication (2FA) is an additional layer of authentication beyond a username and password. 2FA involves something that you know (password) plus something that you have with you (like a cellphone or tablet) to prevent someone from logging in with only your password. With Duo 2FA, you still enter your username and password. The second factor provided by Duo is simply an added layer of security on top of your existing credentials.
Two steps are required for successful access:
- Something you know (UHD username and password)
- Something you have (a Duo-enrolled device/typically a mobile phone)
