-<code>'''getty'''</code>, short for "get tty", is a [[Unix]] program running on a [[host computer]] that manages physical or virtual [[computer terminal|terminal]]s (TTYs). When it detects a connection, it prompts for a username and runs the '[[login]]' program to authenticate the user.
-Originally, on traditional Unix systems, getty handled connections to serial terminals (often [[Teleprinter|Teletype]] machines) connected to a host computer. The ''tty'' part of the name stands for ''Teletype'', but has come to mean any type of [[text terminal]]. One ''getty'' process serves one terminal. In some systems, for example, [[Solaris (operating system)|Solaris]], ''getty'' was replaced by [[ttymon]].
-[[Personal computer]]s running [[Unix-like]] [[operating system]]s, even if they do not provide any remote login services, may still use ''getty'' as a means of logging in on a local [[virtual console]].
-Instead of the ''login'' program, ''getty'' may also be set up by the [[system administrator]] to run any other program, for example pppd ([[point-to-point protocol]] [[daemon (computing)|daemon]]) to provide a dial-up Internet connection.
