Two-Factor Authentication (2FA) Rollout with Duo

What is Duo?

Duo is a two-factor authentication (2FA) service that can be integrated with websites, VPNs and cloud services. The Duo service can work with smartphones, personal computers, land lines and security tokens.

Two-factor authentication increases the security of online communications by making it harder for someone to masquerade as an authorized user. Duo's authentication factors are something the user knows (username and password) and something the user possesses (a device). Someone may be able to steal or guess the username and password but without verification from the user's device, they will not be able to use the login information.

Duo offers the following two-factor authentication options:

  • One-tap authentication using Duo’s mobile app

  • One-time passcodes (OTP) generated by Duo’s mobile app

  • One-time passcodes delivered to any SMS-enabled phone

  • Phone call-back to any phone

  • One-time passcodes generated by an OAuth-compliant hardware token

  • TouchID (currently available on new Macs using the Chrome browser)

In the near future, all Dartmouth services will be protected by Duo's 2FA, so you will be using Duo more often as a method of secure access.
