LOG IN – Origin

The terms Log in and Login have their origins in the early days of computing, particularly in the development of time-sharing systems in the 1960s.

In these early systems, users would have to physically log in to a terminal using a username and password to gain access to a shared computer system. This process was known as “logging in” because it involved recording the user’s activities on the computer system.

The verb log means: to put information in an official record or write a record of events SOURCE

As computing became more widespread in the 1980s and 1990s, the term “Login” began to gain popularity as a way to describe the credentials used to gain access to a computer system or website.
