Install the Okta RADIUS Server Agent for Windows
This topic describes how to install the Windows RADIUS agent.
- When you install the RADIUS server agent, use an account with the Super Admin role. Or use another role that has read-only admin and app admin permissions assigned to it.
- Use a dedicated service account on your server to authorize RADIUS server agents. This ensures that authorizations aren't tied to a user account. These authorizations could be lost if the user leaves the organization.
- Give appropriate admin permissions to service accounts used for RADIUS server agents. See the Multifactor Authentication section of Standard administrator roles and permissions.
- In the Admin Console, go to .
- Scroll to Okta RADIUS Server Agent (EXE) and then click Download Latest.
- Run the installer. Click Next on the initial Important Information and License Information pages.
- Choose a location for the Installation folder and then click Install.
- Optional. Enter your proxy information on the Okta RADIUS Agent Proxy Configuration page.
- Click Next.
- On the Register Okta RADIUS Agent page, enter the complete URL for your org, like https://mycompany.okta.com. For testing in your preview org, you can enter the URL for your Okta Preview Sandbox org, like https://mycompany.oktapreview.com.
- Click Next. The Okta Sign In page appears.
- Sign in to the service-specific Okta account.
- Click Allow Access.
- Click Finish.
