Captive portal Login

Good morning;
In the meantime, I apologize because I am not good at English and I have to use a translator.

I wanted to ask if it is possible to develop an addon in the captive portal where self-registration can be done via sms (for example skebby) or social login.
possibly even if there is the possibility to manually insert specific users.
This request for the development team arises from the needs that are used to create a true automated public hotspot.

if any developer can consider this request i would be grateful.

p.s. sorry but I’m new to the forum I hope I have not done something wrong in case I apologize in advance.
