ThinC-AUTH BioPro

The ThinC-AUTH BioPro is a USB based Security Key with support for Biometric PIV & FIDO2 authentication standards. When using the AUTH BioPro for Smart-card logon, a separate card reader is not required.

ThinC-AUTH BioPro works with AzureAD Certificate Based Authentication (CBA), Local AD SmartCard Login, RDP and Windows Server machines

A PIV (Personal Identity Verification) uses certificate-based authentication (CBA) enables enterprise users to securely authenticate to access controlled resources (Servers, Workstations, Applications etc.) and information systems at the appropriate security level.

ThinC-AUTH BioPro also works with Azure Active Directory and Microsoft Account to access Microsoft Cloud Services, including Microsoft 365, Microsoft Dynamics 365, and Microsoft Azure with a simple touch of a fingerprint authentication using FIDO2.


Supports hybrid

Users can now sign in to Windows on both Azure AD and Hybrid Azure AD joined devices
