Basically if you do some 2 step authentification then apache doesn’t allow to connect without password. Depends which auth do you use. But if you are up to date then it’s a good solution how to keep your OTRS public and secure. But I think your solution could be in configuring apache allow directives.

Sorry, I could not understand how Google Auth would help me limit the user IP address access to the OTRS system.
Would you ellaborate a bit more?
I tend to prefer a in house solution without external APIs, but is just a matter of understanding how Google Auth can help.

Thanks,
Atenciosamente,

We are using 2 step authentification - Google Auth and https and allow acces from outside too.
