I lost my passphrase and now I can’t access the localhost. I tried reinstalling but it didn’t work. How can I start from scratch?
Do you mean the passphrase for a backup or the password for “Access to user interface”?
If you want to start all over, you have to delete the Duplicati data folder. Most likely this is
%LOCALAPPDATA%\Duplicati. If you run Duplicati in portable mode (using the
--portable-mode switch), delete the folder
data located in the Duplicati program folder.
