The Access Control mod is a simple solution to security and key card access in Minecraft. It takes the basic functionality of a button but maximizes its potential by making access panels only accessible via color coded key cards.

All it takes is installing an access panel to whatever door or redstone circuit you’d like to secure. By shift+right-clicking, the panel can be color coded, named and can also contain a whitelist of available players that have access to it.

The Access Administrator is where you can create the access cards for the panels. Here you can customize a color combination for a single card or stack of cards as well as assign which panels the cards have access to or don’t have access to.

And now you have an access card for your newly secured door or redstone circuit!
