Flexible authentication for secure access

Duo Mobile strengthens account security by requiring a

second verification step

after a password is entered. Depending on the service, users can approve a login through a

push notification

or enter a

time-based passcode

generated by the app. Push approvals require an internet connection, while time-based passcodes remain available offline, making authentication possible even when connectivity is limited.

For Duo-protected accounts, setup begins by activating the app through the organization's or service provider's enrollment process.

Camera access

is requested only to

scan QR codes

during activation, although alternative activation methods are also available. Duo Mobile also includes

Duo Wear

, a companion app for compatible Wear OS smartwatches, allowing users to approve login requests or access passcodes from compatible wearable devices.

Reliable authentication for everyday security

Duo Mobile provides a straightforward approach to multi-factor authentication for organizational and personal accounts. Its combination of push approvals, offline passcodes, and Wear OS support makes it a dependable choice for securing accounts across a variety of devices and services.
