The OTP authentication module for Microsoft ADFS, compatible with both ADFS 2019 and ADFS 2016 servers, facilitates multi-factor authentication (MFA) through a Time-Based One-Time Password (TOTP) mechanism, adhering to RFC6238 standards. This MFA solution mandates that users input a one-time passcode generated by authenticator applications like Microsoft Authenticator, Google Authenticator, or Symantec VIP to finalize their second factor authentication during the login process. Additionally, it allows for self-registration via QR codes using free mobile apps, while securely storing OTP data in Microsoft Active Directory attributes or MS SQL Server. Encryption of QR secrets is implemented using AES 256-bit technology, enhancing security further. The configuration also includes specifying network locations (both IPv4 and IPv6) from which users can scan the QR code, and it supports trust relationships across multiple ADDS forests, making it a highly versatile security solution. With these features, organizations can effectively bolster their security protocols and ensure a robust authentication process.
