We strongly recommend that you not pass along your XING login data to any other application on other social networks. At present, XING has not yet granted authorization for any application programmed by a third party to request your login data. For your own security, we blocked a XING-sync application which appeared on facebook last night. If you happened to try out the application (i.e., if you typed in your login data), we recommend you change your password immediately.
We do our best to ensure your security on XING, and ask you to do so as well. It´s an honor that you trust our brand with your private data, and that as a result you´re probably more likely to fill in information where the XING brand appears. Please contact us, however, if you see an application and you´re not sure if it is an official and approved XING application.
For those of you who are interested in doing even more in your XING experience, we are currently working on developing an API for the site. In the near future, everyone who wants to use this API to write an application for XING will have to contact us, and will most likely be granted permission. This way we can keep track which members are using this interface, and continue to make sure that your credentials remain secure.
