{{ApiRef("HTML DOM")}}
The username property of the {{domxref("HTMLAnchorElement")}} interface is a string containing the username component of the <a> element's href. If the URL does not have a username, this property contains an empty string, "".
This property can be set to change the username of the URL. If the URL has no {{domxref("HTMLAnchorElement.host", "host")}} or its scheme is file:, then setting this property has no effect.
The username is {{Glossary("Percent-encoding", "percent-encoded")}} when setting but not percent-decoded when reading.
See {{domxref("URL.username")}} for more information.
