What is multi-factor authentication?

Multi-factor authentication adds a second layer of security to your online accounts. Verifying your identity using an additional factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.

This additional factor of authentication is separate and independent from your username and password — Duo never sees your password.

How It Works

  1. Enter username and password as usual

  2. Use your phone to verify your identity

  3. Securely log in

Why do I need this?

Passwords are surprisingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account. Multi-factor authentication helps keep your account secure even if your password is compromised. With Duo Push, you'll be alerted right away (on your phone) if someone is trying to log in as you.

DoIT strongly encourages Duo users to enroll a backup authentication device to avoid being locked out of your account should you be without your default device!
