Hi guys need your help.

Any Mikrotik router have feature for facebook wifi?

I guess it uses some facebook API to authenticate users (instead of local RADIUS or hotspot).

If that, simply
NOT.

If NOT that, still simply
NOT.

If you mean login to your HotSpot (NOT Facebook Wi-Fi) with Facebook login,
if I do not remember bad, this is disabled some times ago and I do not check later if is possible again.

That face book crap was like 8 years ago now.

Most have stopped using it years ago.
