Definition of login

The word "login" originated in the 1960s in the computing and telecommunications industry. During this time, computers and terminals were used to access remote systems, networks, and mainframes. The term "login" comes from the phrase "login name," which referred to the unique identifier and password used to access these systems. When a user entered their login name and password, they were "logging in" to the system. The act of entering the login credentials was called "logging in," and the process of authenticating the user was known as "logging on." The term "login" was first used in the early 1960s by IBM, and it quickly became a standard term in the computing industry. Over time, it was shortened to "login" and is now widely used to describe the process of accessing a computer system, network, or website using a set of login credentials.
