I didn't find https://pypi.org/project/keyring helpful. Installing dbus-python didn't change the behavior and it's unclear which username and password keyrings is looking for. Are we talking email credentials username and password? What if you wanted to use a different knockknock service like Slack, would the keyrings username and password credentials specified need to be different?
