OpenID eliminates the need for multiple usernames and passwords for different websites and simplifying the online experience of the visitor. Visitors choose their own provider to securely store their identity, and from any other website they can use these credentials to log in. OpenID is an open standard, with security and visitor privacy as main focus areas. It does not collect or exchange any other personal information then strictly needed for remote identification.

This eXtension demonstrates how you can use OpenID alongside your SDL Tridion Outbound Email implementation. In the example, you can authenticate your visitors using their OpenIDs and allow them to change their profile information.

OpenID is an open source authentication mechanism that allows you to login to sites using credentials that you might have with other OpenID providers. This prevents the user from having to remember various different login credentials.

  3. To test this example, create an OpenID at google, yahoo, myopenid,
  4. This project was created on a system that uses the IDENTIFICATION_KEY and IDENTIFICATION_SOURCE as the ContactIDFieldNames. No MandatoryExtendedDetails were configured. In the supplied code, the IDENTIFICATION_SOURCE is OpenID.
