Duo Multi-factor Authentication
Quicklink(s)
Duo adds an extra layer of account security by requiring you to verify your identity through a second factor, such as a phone or token, in addition to your password.
Upgrade to Duo 4.49 or higher by March 17, 2025
Beginning Monday, March 17, 2025, if faculty, staff or student’s devices are not running Duo Mobile version 4.49 or higher, they may have issues authenticating in Duo using the mobile passcode, resulting in a loss of access to services requiring UCI Single Sign On (SSO). After the update, they will still be able to use Duo push for authentication.
What is Duo?
Duo is a multi-factor authentication application. It adds a second layer of protection by requiring you to verify it’s you after you login with your UCInetID and password. You use something you know (your password) plus something you have (a smartphone or device). This extra layer of protection prevents anyone but you from logging into your account, even if they know your password.
Duo + UCInetIDs
Every account that uses your UCInetID will require Duo to verify it is you. All employees and students need to be enrolled in Duo and have it set it up when logging in to any system with your UCInetID and password.
UCI Duo supports a range of electronic devices including:
- iOS smartphones and tablets
- Android smartphones and tablets
- Hardware tokens, such as OIT-issued tokens or third-party tokens like YubiKey
