Run your own identity server

Running your own identity server allows you to act as an OpenID Provider. You could run one just for yourself, for a community of users or, if you wish, for the general public. You do not need to register or obtain permission from anyone; you just need to run an OpenID identity server on your site. This requires the ability to install and run some software on your web server. Some existing OpenID identity server implementations are listed below.
