What is a Login ID ?

Login ID – Identification code used when logging on to a system, which permits the system to recognize the user. May be associated with varying levels of security.

The user name, or username, by which a person is identified to a computer system or network. A user commonly must enter both a user ID and a password as an authentication mechanism during the logon process. If the system or network is connected to the Internet, the username typically is the leftmost portion of the e-mail address, which is the portion preceding the @ sign. In the e-mail address [email protected], for example, ray is the username. User ID is synonymous with username.

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. Often, the user ID must conform to a limited length such as eight characters and the password must contain at least one digit and not match a natural language word. The user ID can be freely known and is visible when entered at a keyboard or other input device. The password must be kept secret (and is not displayed as it is entered). Some Web sites require users to register in order to use the site; registered users can then enter the site by logging on.

Logon is also used as a modifier as in “logon procedure.” The verb form is two words: to log on.

In UNIX-based operating systems, logon is called login. The procedure is called “the login procedure.” and the verb form is: to log in.
