Frequently asked questions

What is Duo Push?

Duo Push is the notification Duo Mobile users approve when logging into protected accounts. The push notification acts as a secure method to verify the user’s identity in the MFA process.
How long does Duo Push last?

A Duo Push notification expires after 60 seconds. After that, a new notification may be required for authentication. A time-based code or authentication request is valid for only a limited time to reduce the risk of unauthorized access to protected accounts.
What is the difference between a push notification and a text message for MFA?

A push notification is generated by an application, such as Duo Mobile, and contains a secure code or approval request. On the other hand, text messages used for MFA or 2FA rely on SMS, which is less secure due to risks like SIM swapping and interception.
How do I get Duo Push?

Verified Duo Push is available to all Duo Essential users. Duo makes it easy for new users to register their phone or tablet and activate the Duo Mobile application to start receiving Duo Push notifications for secure account logins. New users can follow simple steps in Duo’s Enrollment Guide to self-enroll.
Is Duo Push more secure than SMS?

Duo Push with the Duo Mobile authenticator app is more secure than receiving 2FA codes via SMS. SMS authentication is vulnerable to SIM-swapping attacks or interception due to its reliance on the cellular network. Duo Push uses cryptography to ensure that it’s communicating with the right device.
