What is Duo?

Details

Duo is a tool that allows for a more secure level of authentication than just a NetID and password. This is called two-factor authentication.

Two-factor authentication adds a second layer of security when using your Dartmouth NetID and password to sign in to certain services. 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. Once you've enrolled in Duo you're ready to go: You'll login as usual with your Dartmouth NetID and password, and then use your device to verify that it's you. The verification can be done in many different ways: via text message (SMS), voice call, one-time passcode, the Duo Mobile smartphone app, 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. With Duo, you'll be alerted right away (on your phone) if someone is trying to log in as you.

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