Duo Mobile

Secure Two-Factor Authentication App

Secure access to work and personal, cloud and on-premises apps with one simple app - Duo Mobile.

Easy, One-Tap Authentication

Logging in securely is fast and easy with Duo Push, the more secure method of two-factor authentication supported by Duo Mobile. Users quickly verify their identity by approving push notifications before accessing applications. They can easily stop fraudulent attempts to access company data by tapping the deny button.

Duo Mobile can also generate time-based one-time (TOTP) passcodes that users can type into their login prompt to complete the two-factor authentication process.

  • “Prior to Duo Mobile, we did not have two-factor security. As we move our applications to the cloud we decided to move to two-factor authentication. The combination has eliminated the issues we were having. It is a great tool. I am amazed how easy it was to have up and running and maintain.”

    — Robert Rose, CFO, Dairy Records Management Systems
  • “Duo made two-factor authentication both easier to support and easier for users to live with (namely with Push verification). User buy-in is key to being able to improve security and Duo made that far easier.”

    — Rajeev Chopra, President, MIS
