This article describes how to enable Nexus OTP in Nexus Hybrid Access Gateway as two-factor authentication method for SafeInspect, to replace static passwords.

Nexus OTP can be either Nexus TruID Synchronized or Nexus Personal Mobile OTP, or any other OATH-based mobile OTP application, such as Google Authenticator or Microsoft Authenticator. 

With the setup described in this article, Nexus Hybrid Access Gateway functions as a RADIUS server and SafeInspect as a RADIUS client. Nexus TruID is used as an example below and is available for iOS, Android, and Windows.

  1. The end user starts the TruID client and enters the PIN in TruID to generate an OTP.
  2. Cyberoam request the end user to enter username, password and OTP.
  3. The end user enters username, domain password and OTP.
  4. The domain credentials are validated by the Active Directory.
  5. The OTP authentication request is relayed to Hybrid Access Gateway Authentication Server via RADIUS.
  6. The authentication server validates the OTP with the associated TruID token and PIN from the user database.
  7. Upon successful validation, the authentication server responds with successful authentication to Cyberoam.

Cyberoam provides access to the end user.
