Since version 1.4.1 duplicacy stores master password encrypted with UUID if keyring is not available which is awesome because it absolves the users from specifying DWE_PASSWORD, instead users need to login to UI once when the installation is moved to a new machine (or container instance) to re-encrypt the credentials.
What UUID is used and how is it determined? I would like to fake and persist it in the docker container, the same way we now persist machine-id.
