About Duo Multi-Factor Authentication

Some OU websites now feature multi-factor authentication during user account login. This feature acts as an additional security measure to protect user data. A comprehensive guide can be found on Duo’s website here.

What is Two-Factor Authentication?

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

How It Works

  1. Enter username and password on the OU website you wish to access as usual.
  2. If this is your first time logging in under Duo, you should be prompted to setup your account and device.
  3. Once your account is configured, use your phone to verify your identity using the Duo App.
  4. Use the passkey the App generates on the OU website.
  5. The website should now securely log you in.

Once you’ve enrolled in Duo you’re ready to go: You’ll login as usual with your username and password, and then use your device to verify that it’s you.

Duo lets you link multiple devices to your account, so you can use your mobile phone and a landline, two different mobile devices, etc.

Why Do I Need This?

Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account. Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. This second factor of authentication is separate and independent from your username and password — Duo never sees your password.
