Description

Please add the details below about this feature in the OpenVPN Custom Configuration Options documentation.
https://docs.netgate.com/pfsense/en/latest/vpn/openvpn/configure-custom.html#renegotiation-time

The use of auth-gen-token offers advantages over the reneg-sec feature and should be the primary option for defining renegotiation authentication with OpenVPN multi-factor authentication.

--auth-gen-token [lifetime]
After successful user/password authentication, the OpenVPN server will with this option generate a temporary authentication token and push that to client. On the following renegotiations, the OpenVPN client will pass this token instead of the users password. On the server side the server will do the token authentication internally and it will NOT do any additional authentications against configured external user/password authentication mechanisms.The lifetime argument defines how long the generated token is valid. The lifetime is defined in seconds. If lifetime is not set or it is set to 0, the token will never expire.
This feature is useful for environments which is configured to use One Time Passwords (OTP) as part of the user/password authentications and that authentication mechanism does not implement any auth-token support.
