The daemon looks at the file <config folder>/auth for doing authentication.
The format of this file is straightforward, each line contains a username:password:level tuple in plaintext.
There should always be a 'localclient' entry for use by the UIs running locally by your user.
Note: If you do not have an auth file in your config folder, first run the daemon to have it created for you.
Deluge 1.2.0 introduces different levels of authentication:
|Level Name||Level Value|
Note: In Deluge 1.3.3 authentication levels don't do anything. In the future they will. In git master there is a multiuser option that makes use of authentication levels.
Example of an auth file:
localclient:a7bef72a890:10 andrew:password:10 user3:anotherpass:5
Example of adding a new user under Linux:
echo "username:password:level" >> ~/.config/deluge/auth
From the GtkUI, you will have to add the host with a username and password, if you don't do this, you won't be able to connect to the host or tell if it's online.
