usernameThe name people use to identify themselves when logging into a computer system or online service. Spaces are generally not allowed in the username, and in most situations, both a username (user ID) and password are required.
In an Internet email address, the username is the part before the @ sign. For example, KARENB is the username in email@example.com. AOL calls a username a "screen name."
A Username Can Be an Email Address
For some sites, a person's email address can be used instead of making up a name. Sometimes a username must be the email address (see below).
|Username or Email Address?|
|These Google mail server settings ask for "User Name" when, in fact, an email address must be entered and not some made-up identity. Many websites create confusion like this and may even ask for "username" in one dialog and "email address" in the other.|
