I’m currently trying to spin up a new server stack including qBittorrent. when I launch the web UI, it asks for a login on first launch. According to the documentation, the default user id admin and the default password is adminadmin.

Solved:

For qBittorrent ≥ v4.1, a randomly generated password is created at startup on the initial run of the program. After starting the container, enter the following into a terminal:

docker logs qbittorrent or sudo docker logs qbittorrent (if you do not have access to the container)

The command should return:

******** Information ******** To control qBittorrent, access the WebUI at: http://localhost:5080 The WebUI administrator username is: admin The WebUI administrator password was not set. A temporary password is provided for this session: G9yw3qSby You should set your own password in program preferences.

Use this password to login for this session. Then create a new password by opening http://{localhost}:5080 and navigate the menus to -> Tools -> Options -> WebUI ->Change current password. Don’t forget to save.
