OpenID is turned off by default, but you can easily enable it for your site:
  1. Make sure you’re logged in as a site administrator.
  2. Go to Site Administration > Settings > Authentication.
  3. After Add New Authentication Source, select OpenID, then click the Add button.
  4. Pick a Name for your OpenID source. This is how this authentication source will appear on the sign-in page for your users. Pick something that will be easy for your users to understand and recognize.
  5. Hit the Save button.
