I was actually wrong. It's just a general head authcode. The other two are sec and medical. A couple more are rolled at the beginning of every round too, but I was referencing the ones on the authentication disk.

As for making it safer, I'd say if you limit it to CE and make it packet-controlled then it would actually make things more dangerous. Especially if you made the packet without an access code - or used the standard head code you can get from dwaine with little effort.
