Wifi guest account manager can reset root password

[philippe.hyvernat]

Hello all,
It is my first message on the Opnsense forum.
I setup a captive portal with wifi guest and create a group "wifi-manager" with a user in this group.
This group can only access to "system:access:user".
I wanted this user can only create guest account.
After login with the wifi-manager user, the restrictions are enables but the user can interact on the root account or other admins account.
Is it possible de hide admin account from this group or user ?

Is it possible to print the guest account information to send to the guest user ?
Thanks a lot for your answer
