About the Okta RADIUS Agent

The Okta RADIUS Agent is a lightweight program that runs as a system service. It includes these features:

• Tunnels communication between on-premises services and Okta.
• Delegates authentication to Okta using single-factor authentication (SFA) or multifactor authentication (MFA).
• Supports the Password Authentication Protocol (PAP).
• Supports the Extensible Authentication Protocol Generic Token Card (EAP-GTC).
  
• Supports EAP Tunneled Transport Layer Security (EAP-TTLS) with PAP as the inner authentication protocol within the secure TLS tunnel.
• Supports the User Datagram Protocol (UDP), defaulting to port 1812, using multiple ports simultaneously.
