What is a login system?
In general computer usage, logon is the procedure used to get access to an operating system or application, usually in a remote computer. Almost always a logon requires that the user have (1) a user ID and (2) a password.
Is A username and password the same thing?
The username is an identifier: it tells the computer who you are. In contrast, a password is an authenticator: you use it to prove to the operating system that you are who you claim to be.
What is login and password?
To identify yourself to the operating system, log in by typing your login name (also known as your user ID or user name) and a password. Passwords are a form of security. People who know your login name cannot log in to your system unless they know your password.
