Move to Duo

Data is double secured with Duo

What is Duo?

Duo is a multi-factor authentication app that makes it much harder for hackers to access your UC Davis accounts. Even if someone has stolen your passphrase, they need a “second factor” — in most cases a temporary numeric code, to access your account.

Duo's New Login Experience

Beginning November 1, 2023, Duo will upgrade its login experience to a Universal Prompt. Aggies will see an updated screen directing them to verify their identity. Users can rest assured this is the same Duo they know and trust, just with a new look designed to work faster and strengthen security. No action is required on their part to trigger this change.

As a security protection, Information and Educational Technology (IET) is reminding you to approve only login attempts that you have initiated and reject authentication requests that you are not expecting.
