I use Sync 2.0 on my laptop. I want to run a headless Sync 2.0 server instance on my ubuntu vserver. Therefore I created a configuration file for my btsync instance in /etc/btsync/instance.conf. In instance.conf I can define all the shared_folders. To sync them with my laptop I have to set a secret for each directory to sync. How can I find out the secret key for this configuration parameter in the Sync 2.0 App for Mac? I can only get a weblink or an QR-Code. That does not work as a secret parameter. Any tipps?
