I think the desktop clients need to have a import/export settings file which can be saved in a unencrypted or encrypted format. This settings file will save the settings and sync connections.

The reason I think this is needed is for when one wants to go though border security such as at an airport. One can easily export their settings to the cloud or on their laptop. Logout of Nextcloud, uninstall Nextcloud, delete the folders that were synced with Nextcloud, go through security and then install Nextcloud, login and import the settings and have Nextcloud setup the same way it was before.

This will make it easy to setup Nextcloud again once your passed security. And is a useful feature to protects ones privacy.
