AusweisApp2 Preview is a mobile application developed by Governikus GmbH & Co. KG. This free app is designed to provide previews of functions that will be included in a subsequent version of the AusweisApp2 product. It enables users to identify themselves securely on the internet using the online identification function of the identity card and the electronic residence permit. The app supports identification via NFC and Bluetooth card readers, and it allows users to activate and change their PIN at any time.

In addition, AusweisApp2 Preview allows users to check what data is stored on their ID card and view an overview of services that have already integrated the online ID function. Users can also create a history of their authentications. However, it is worth noting that not all mobile devices have the requirements for mobile ID. The app maintains an overview of supported devices, which is available on the developer's website.

Overall, AusweisApp2 Preview is a useful app for anyone who needs to identify themselves online securely.
