getty, short for "get tty"

Unix program running on a host computer that manages physical or virtual terminals (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 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, getty was replaced by ttymon

Personal computers running Unix-like operating systems, 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) to provide a dial-up Internet connection
