Duo 2FA

DUO Two-Factor Authentication is a proprietary service which provides 2FA through PAM modules and a web-browser login page. While VTLUUG concurs that 2FA is a good practice, DUO is an ineffective, buggy, and anti-freedom solution.

Issues

DUO 2FA has a number of disadvantages and issues. To list a few:

• A cellphone, compatible tablet, or landline is mandatory to enrollment in 2FA
• U2F is exclusively supported in the Chrome and Chromium browsers, despite the presence of a functional plugin which provides the feature in Firefox
  • Duo login page is actually broken by use of this plugin
• Privacy policy is a joke, and implies almost no level of customer or customer data protection
