I’ve set up Nextcloud and want to use encryption on server base. But all documentation is talking about the ‘master key’ to restore files in the future (if needed). But I did not enter any master key ever and it was not displayed to me to save it on a safe place.
Is the master key the same as the admin password you entered the first time? Or is it an other and if so, how do I get it to store it in a safe place?
