A user using a browser having stored authentication information for a web service in a first domain is authenticated to a web service in a second domain. The browser is provided with computer program instructions causing the browser to transparently provide the stored authentication information to the service in the first domain, receive cross-domain authentication credentials from the service in the first domain, and provide the cross-domain authentication credentials to the service in the second domain. The service in the second domain validates the cross-domain authentication credentials. If the credentials validate, the service in the second domain transparently provides the user with authenticated access. |
