I would like to have theses options:
-Can change the time the passcode is valid. By default, it could be set to 24h, but we can change it (for examble: 48h or 1 week).
-As an administrator, I would like to easily click on a button to reset it passcode and sent it by email (I think send it by email could be done with another module).
-Have the option to enable/disable IP address source

Thanks.
It's a great module.
