A back door is a rear or secondary entrance to a building, as opposed to the front door.
By extension, back door describes indirect or unofficial routes: a back-door deal, back-door negotiations.
In computing, a backdoor is a hidden method of bypassing security to access a system—sometimes built in deliberately, sometimes exploited by hackers.
