Duo Mobile

Secure sign-in support for work and personal accounts

Duo Mobile is a two-factor authentication app for people who need an extra check when signing in. It is especially suited to employees using an organization protected by Duo Security, while also supporting third-party accounts that use standard two-step verification. The app is developed by Cisco Systems, Inc. and listed in the Business category.

Push approvals and one-time codes

For Duo-protected logins, the app can send a push request to your phone. You can review the sign-in details shown and approve the request from the notification screen. Duo Mobile also generates time-based one-time passcodes, giving you a way to authenticate when a network connection is unavailable.

A central place for supported accounts

Duo Mobile can hold authentication entries for services beyond Duo Security, including accounts activated through QR codes. This makes it useful as a shared 2FA tool rather than only an organization-specific sign-in companion. The layout keeps the main approval and code functions easy to reach, although people managing many entries may find the account list limited in its organization options.

Worth knowing before setup

Organization-managed accounts generally require an enrollment or activation link from an administrator, so setup depends on how your workplace handles access. Once connected, the app focuses on quick approvals and readable account details instead of adding extra layers of navigation. Support for Wear OS can also let compatible users respond to authentication requests from a smartwatch.
