Secure Access with the Duo Mobile Authenticator App

Secure all your devices with one simple and easy authentication app: Duo Mobile.

Easy, One-Tap Authentication

It's fast and easy to log in securely with Duo Push, the more secure method of two-factor authentication supported by Duo Mobile. With Duo's single-tap, user-friendly interface, users can quickly verify their identity by approving push notifications before accessing applications. It's just as quick to deny an unfamiliar login attempt, so users can easily stop fraudulent attempts to access company data.

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.

User-Friendly Security Features

Duo Mobile helps users take an active role in protecting their accounts.

Security Checkup

By providing a security score of users’ devices, Security Checkup empowers users to maintain the security hygiene of their mobile devices via Duo Mobile notifications. This feature is available on iOS and Android through Duo Mobile.

Duo Restore

Provide your users with the ability to back up and restore their Duo Mobile app with Duo Restore. This feature allows Android and iOS Duo Mobile users to back up their Duo-protected accounts and recover them when they get a new device — no help desk ticket needed.

Authentication Controls for Every User

Duo Mobile supports multiple authentication controls — from push notifications, to biometrics, to passcodes — while maintaining a consistent, intuitive user login experience. Allow your users to choose the method that best meets their needs and easily update their preferences at any time.
