The FAP feature was developed by Forumer to enable owners to take control over their boards should they get demoted for whatever reason. Basically all it was was a drop down list of all members of the forum and a "Make admin" button so if you got deleted or otherwise demoted you could for example register a new account for yourself, log in the FAP on your original username and pass and make your new account admin and that way take control of your board....or you could make anyone admin. No other managing of anything else was possible through FAP.

Unfortunately it's not working at the moment. It is on the list to be repaired but I can't tell you when.

You can always protect yourself by making a spare admin account with full access to the admin CP and hiding it and also by restricting the other admins' access to only the necessary features... hide the whole root admin group and don't use any of the account in it for posting on the board, make another admin group and use the account from there that way no one knows about your security account and should anyone turn on you you can always take back control...
