A login is the process or information used to enter a computer system, website, or app, usually involving a username and password. As a verb phrase, “log in” means to perform this action.
It comes from “log,” meaning to record events, and “in,” suggesting entry into a system. The word grew with early computer systems that recorded who accessed them and when.
“Login” sounds simple, but it’s the tiny doorway that protects huge amounts of personal and financial data. Every extra step—like two‑factor codes—is really an attempt to make that doorway harder for invisible strangers to sneak through.
