Add User to the authentification file Create a Deluge user for clients/UIs to access the daemon by editing the authentication file, auth, located in the above config location. The auth file should consist of lines of <username>:<password>:<level>. Replace <username> and <password> with your choice and <level> with the desired authentication level. You can use your favourite text editor to achieve this or can be done with a one-line echo command e.g.: echo "alice:MyC0mpL3xPass:10" >> ~/.config/deluge/auth
