connecting to hotspot by mac address for unidentified users

hi everybody
i have set up a hotspot with user manager and users log in with their accounts . know i want the users who do not have account , by clicking a link in the login page , be able to connect with a specified profile applied to them .
thanks

Look for “trial” hotspot user setup.

thanks for your reply , I want to apply the profile from user manager not hotspot profile

Not sure if that is doable, but even if it were, why bother? A trial user is always going to be that, a trial user with a limit either by transfers, or time. In the end, is just a single profile for a single user on the hotspot.
