Understanding Duo Push and Passcodes
With your account activated, Duo Mobile offers two primary methods for authentication: Duo Push and passcodes.
Duo Push
Duo Push is the recommended and most user-friendly method. When you log in to a Duo-protected application, a push notification is sent to your Android device. Simply tap Approve on the notification to verify your login.

If you receive a Duo Push request you didn’t initiate, tap Deny and report it as suspicious to your organization’s administrator.
Passcodes
In situations where you don’t have internet access or prefer not to use push notifications, Duo Mobile can generate time-based passcodes. To get a passcode, simply tap on the account within the Duo Mobile app. A unique, time-sensitive passcode will be displayed. Enter this passcode into the login prompt to authenticate.

Furthermore, Duo Mobile includes a Security Checkup feature. This tool verifies your device settings against recommended security configurations and alerts you to any potential issues, helping you maintain a secure mobile environment.
