What is the first step to set up two-factor authentication with a remote server?

The initial step in setting up two-factor authentication with a remote server is to point the RADIUS server to the FortiAuthenticator. This action establishes the initial connection required for the two-factor authentication process to operate. By directing the RADIUS server to the FortiAuthenticator, you are essentially enabling the FortiAuthenticator to process the authentication requests sent from the server, which is crucial for verifying the user's identity through an additional factor, such as a token.

This integration allows the FortiAuthenticator to handle the authentication and ensure that the second layer of security is in place by requiring something that the user has, such as a FortiToken. Once this configuration is in place, other steps, like configuring FortiToken settings or creating admin accounts, can be carried out effectively under the framework that has been established.
