Hello, I would like to insert a hotspot to authenticate by password generated and sent by sms. Something of this kind the user called was introduced his cell phone number, a sms was sent to the user with the user and pass (user his phone number, and password is generated randomly by mikrotik)
The sms would be sent by a gsm modem connected to the usb port of the router.

Is it possible and functional to do everything within mikrotik without external servers?
Do you know of an example to use as a basis?

Regards
Tiago
