With multiple passcode configurations, native hardware tokens, and integrations with a broad range of third-party devices, Duo is an easy-to-use two-factor authentication solution that fits seamlessly in your users’ daily workflows.
Some websites and online services let users protect their accounts with a mobile-generated passcode that must be manually entered and only works for a certain amount of time — typically 30-60 seconds. Duo Mobile can generate these time-based one-time passcodes (TOTP) for all third-party sites, letting users keep all of their accounts in one app.
Users without Internet connectivity or smartphones can still authenticate easily with Duo’s SMS passcode or phone callback options.
To generate an SMS passcode, a user logs into an application with their usual account credentials. Duo will then send them a one-time passcode via text that can be typed into a two-factor authentication prompt on the user’s device.
To use phone callback, simply call any phone number enrolled to a user and let them confirm their identity by answering the call and pressing a key. Access keys can easily be configured and managed via Duo’s administrator dashboard.
When other two-factor authentication methods aren’t an option, you can manually generate a bypass code. This feature comes in handy when you need to provide temporary access for a contractor or vendor, or when an employee forgets their laptop or phone but still needs to access their applications.
Duo also lets you manually prevent logins. If a user loses their authentication device or reports it stolen, Duo lets you disable and disassociate the device from the user. You can also re-enable the device if found, and send a new activation link for Duo Mobile by SMS or email.
Duo supports standalone, one-time password hardware devices for two-factor authentication — and thanks to Duo’s flexibility, choosing the right one for your business is easy.
Duo supports third-party hardware tokens, like Yubico’s YubiKeys, or any OATH HOTP-compatible tokens. Third-party hardware tokens can be imported into the system by an administrator.
Duo’s D-100 tokens have an expected minimum battery lifetime of 2 years. They are only available in increments of 10. You can purchase tokens from the Duo Admin Panel or through your Account Team.

Duo Push is our most commonly-used second factor of authentication, thanks to its simplicity and reliability. Users just download the Duo Mobile app and are automatically prompted to confirm each login attempt — all it takes is a single tap.
Duo allows users to physically authenticate by tapping a U2F USB device or using a built-in biometric authenticator, such as TouchID, via WebAuthn.
