# Kerberos

Essential · [Official website](https://tools.ietf.org/html/rfc4559)

Kerberos is a network authentication protocol. On the web it is used through HTTP Negotiate (SPNEGO, described in RFC 4559) so that users already signed in to a corporate domain can access intranet sites without typing a password again. It is an authentication mechanism rather than a tracking tool.
