Hi,
Terms and conditions can be enabled by navigating to Services -> Hotspot -> Edit instance -> Advanced -> Enable TOS.
To require only the password without a username, you will have to choose MAC authentication in Hotspot settings -> General. Then, a new toggle slider to require a password will appear. Enable it. You can also set the password on the same page.
You can also assign a user group to this hotspot instance. It is possible to create a user group and configure download/upload limits and other rules that apply to that user group. To manage user groups, navigate to Services -> Hotspot -> User groups.
You can find more information about Hotspot HERE.
Hotspot 2.0 HERE.
Kind Regards,
Andzej
