Duo Mobile is a two-factor authentication (2FA) app that adds an extra layer of security to any online account. It provides an easy and secure way to access and manage your online accounts. The app works on both iOS and Android mobile devices. It requires users to enter a unique passcode, which is sent to their device via SMS, email, or the Duo Mobile app itself. Once the user has entered the passcode, they will be able to access their account. Additionally, Duo Mobile also provides users with the ability to approve or deny access to their accounts from their mobile device. It also features an optional security feature called "Duo Push" which sends an additional notification to the user's device when someone attempts to log in to their account. This helps prevent unauthorized access to an account.
