What Does Duo Mobile Actually Do?
Duo Mobile receives organization sign-in requests, generates offline passcodes, scans third-party OTP accounts, and reports selected device security signals when an administrator enables trusted-device policies.
Individuals usually cannot choose Duo unless a service or employer deploys it. New-phone restoration depends on prior backup and administrator settings, while work policy may inspect device posture.
