For authentications against external services, Open-Xchange has now imple-mented oAuth, and oAuth will be used whenever a service supports it. Most likely oAuth will become the industry standard for authentication of external services and several services already support it: e.g. LinkedIn, Twitter, and Facebook.

Using oAuth has several advantages compared to existing implementations used in the Open-Xchange user interface: With the new authentication method, users only need to authorize once to an external social service. After the initial authen-tication has been done, all additional updates can then be performed without having to login again (well, at least as long as the credentials at the external service remain unchanged).

Please note:
After the update to the new Open-Xchange major version, users will need setup their Facebook? and LinkedIn? subscriptions once more.
