OpenOTP™ RADIUS Bridge
OpenOTP RADIUS Bridge provides the RADIUS RFC-2865 (Remote Authentication Dial-in User Service) API for your OpenOTP server. With RADIUS Bridge you can integrate a large variety of third-party products and systems with multi-factor authentication. Many Enterprise products and services like Microsoft reverse-proxies, VPNs, Citrix or even VMWare provide support for RADIUS servers for a more flexible user authentication.
RADIUS Bridge supports several password mechanisms to handle a two-factor authentication and by design, some One-Time Password methods like on-demand SMS-OTP work better with a challenge-response mechanisms. You can also choose wether the users should be challenged the OTP password after having entered their domain password or should enter the password and the OTP in a concatenated form.
RADIUS Bridge supports single-factor authentication with password-only or OTP-only too. The OpenOTP authentication policies are very flexible and can be configured on a per-client basis in WebADM. Moreover, the client policies can be contextual to the network or geolocation of the users accessing your systems. This flexibility also provides support for integrations where the first factor is handled by your AD servers and the second factor (the OTP) is handled by your OpenOTP server.
RADIUS Bridge provides Two-Factor authentication with all OpenOTP One-Time Password methods:
RADIUS Bridge provides the RADIUS interface on top of OpenOTP server. And it is included in your OpenOTP license at no extra charge.
The RADIUS standard is supported by all major security products on the market. You can also implement OpenOTP authentication methods for:
- VPN Servers (Checkpoint, Cisco, Nortel, F5, Fortigate, Palo Alto…)
- Microsoft DirectAccess VPN
- Citrix (Access Gateway, XenApp, Netscaler)
- VMWare View
- Microsoft Reverse-Proxies (TMG, UAG, 2012 server…)
- Enterprise Wifi (Cisco EAP-GTC and EAP-TTLS-PAP)
- Radius-enabled Linux services (OpenVPN, Apache…)
- And many others…

VPN Authentication with OpenOTP and Radius Bridge
See below the OpenOTP RADIUS architecture diagrams. Scenario one shows a typical OpenOTP integration with an enterprise VPN server. Scenario two includes the WAProxy mobile-to-server communication component which is necessary to enable OpenOTP One-tap login with Approve/ Deny.
