Background
OpenID is a way to login to applications or resources using an existing account that acts as a identity provider. The Fedora project acts as an OpenID identity provider for anyone with a Fedora Account System account.
Using
We have an OpenID provider running named FAS-OpenID.
When trying to log on to an OpenID enabled site, give
username.id.fedoraproject.org
as URL. Example, if your FAS login is JohnDoe, you would enter JohnDoe.id.fedoraproject.org. If you are not logged in to FAS at this stage, you will be first taken to the FAS-OpenID login page. On the first login from each external site, you will be taken to id.fedoraproject.org and asked to approve the OpenID request.
Old provider link
There was an old (and non advertised) link at https://admin.fedoraproject.org/accounts/openid/id/username to the old openid provider. These links are no longer used, you should always use the above link instead.

Feedback
OpenID should work for all websites accepting OpenID login. We are looking for feedback and developers to improve the code. Send feedback to the fedora infrastructure list, #fedora-admin on irc.freenode.net or in a infrastructure ticket.

upstream
FAS-OpenID was written by Patrick Uiterwijk.
A good place to start learning about OpenID and FAS-OpenID would be this classroom.
history
OpenID was first discussed at the 2006 FedoraSummit. The OpenID implementation was completely rewritten from scratch in 2013.
