OneLogin Protect is a mobile authenticator app that generates time-based one-time passwords and supports push notifications for seamless authentication via smartphone or smartwatch. Users can approve logins with a tap or biometric verification using Touch ID or Face ID. The app generates 6-digit codes every 30 seconds and works offline without internet connection. It is compatible with iOS, Android, and wearable platforms, integrating with OneLogin's single sign-on platform and third-party services including VPNs, cloud applications, and OATH-compliant systems. Users can add accounts through QR codes or manual entry, while administrators can enforce MFA policies through OneLogin's portal, including device registration and biometric setup requirements.
