On my previous MyBB installation I had some tweaks on my AdminCP for security:
- Renamed folder. So instead of the AdminCP being under the standard standard /Admin file path, I put it in a renamed folder which was referenced in the config file.
- Password protected the directory access.
- Created a "dummy" login screen in the original admin folder which emailed me when anyone attempted to login.
- Removed the link from the main forum.
