What is Duo Mobile?

Duo Mobile is a popular two-factor authentication (2FA) app developed by Duo Security. It enhances security by requiring users to provide two forms of identification before granting access to accounts or systems. Typically, after entering your username and password, you’ll need to confirm your identity by approving a push notification sent to your Duo Mobile app, entering a one-time passcode, or using other supported methods like biometric authentication.

Here’s how Duo Mobile works:

1. User Logs In: You enter your username and password into the service you’re trying to access.
2. Second Factor Prompt: After the initial login, the service prompts you for a second form of authentication.
3. Duo Mobile App Notification: You receive a push notification on your mobile device via the Duo Mobile app.
4. Approval: You approve the login attempt by tapping the notification, or you can generate a code within the app to enter manually.

This dual-layer security makes it much harder for unauthorized users to access your accounts, even if they have your password.
