How to limit OpenVPN session time?

Question

openvpn

How can I limit the session time for example 1 hour?

What would after connecting, after 1 hour the client disconnected.

Already watched:
$ telnet localhost 7505
$ kill ip:port

They disconnect the client, but he can connect again (autoconnect).

Answer 1

Of course, the user will be able to log in again - the certificate / password is valid for him. Disconnect and kill/change login details.

Answer 2

I have 2FA two-factor authentication - autoconnect does not work and everything falls off. Maybe you need it?
