A piece of code built into software which allows it's creator entry. This type of system is usually unneccecary, but has two main reasons.

1. To automatically create an account with full priviledges that is hidden from the user(s) of the program, so any time they get locked out the creator can log in and solve the prblem for them (a maintenance account)
