Definition, synonyms and related words
A person's identification on an individual computer system.
"When logging into my old work laptop, I had to type in a different username than the one I use for our company server."
In plain English: A username is the unique name you pick to identify yourself when logging into websites or apps.
"Please enter your username to log into the website."
Usage: A username serves as your unique identifier to log into specific online accounts or systems, distinct from the password required for security verification. It is often confused with terms like "email address," but a username can be any chosen string of characters while an email includes a domain name.
The word username is a straightforward combination of the words user and name that emerged as computer technology became widespread. It was formed to describe an identifier used by individuals on digital platforms rather than referring to their real identities.
