Overview
̽»¨´óÉñ RADIUS lets users securely authenticate their devices to WiFi, VPN, or other supported networks using ̽»¨´óÉñ. There are 3 available RADIUS configurations at ̽»¨´óÉñ that vary in complexity based on your preferred authentication method. With password-based authentication, users authenticate with the same credentials they use to access their other ̽»¨´óÉñ-protected resources (for example, the ̽»¨´óÉñ User Portal and SSO applications).
Password-based authentication is the default authentication method for ̽»¨´óÉñ RADIUS.
̽»¨´óÉñ supports the following RADIUS configurations, differentiated by the method with which users authenticate on their devices:
- Password-based authentication (WiFi or VPN)
- Users authenticate to networks with their ̽»¨´óÉñ username or email address and password.
- Reduces the need for additional configuration on end-user devices.
- Passwordless-based authentication (WiFi)
- AKA certificate-based authentication (CBA); this authentication method for RADIUS requires additional configuration steps to connect end-user devices to networks.
- This method requires devices to connect using EAP-TLS.
- Delegated authentication with Entra ID (WiFi)
- Use ̽»¨´óÉñ RADIUS solely as the authentication server and maintain Entra ID as the identity provider (IdP).
- Delegated auth is still password-based, but user credentials are managed in Entra ID.
- This method requires devices to connect using EAP-TTLS/PAP.

Configuring ̽»¨´óÉñ RADIUS
Configuring ̽»¨´óÉñ RADIUS involves multiple steps including the ̽»¨´óÉñ configuration, the networking equipment configuration, and potentially the end-user device configuration depending on your chosen solution within your environment. The following serves as an overview of the process:
- Select the RADIUS configuration appropriate for your environment:
- Password
- Passwordless / CBA
- Delegated Auth with Entra ID
- Based on your preferred authentication method, configure your ̽»¨´óÉñ RADIUS server:
- Next, configure your network hardware to use the ̽»¨´óÉñ RADIUS server:
- For generic configuration applicable to multiple vendors:
- Vendor specific configurations:
- Lastly, configure your endpoints to connect using JC RADIUS:
- WiFi: if you selected Password-based authentication, no further configuration should be necessary. Users will connect from their end-user devices with ̽»¨´óÉñ credentials and will not require any additional configuration on their end-user devices. See Configure your WiFi Clients to use RADIUS for more information.
- VPN: if you selected Password-based authentication, any additional configuration between your VPN service and your end-user device is required based on the specifics of your vendor.
- If you selected Passwordless-based authentication / CBA, see the following information:
- If you selected Delegated Authentication with Entra ID, configure your endpoints to use EAP-TTLS/PAP:
