Cannot login to OSMC with command line

In the process of setting up transmission, I would like to access command line.
I’ve escaped during the splash screen, accessing the terminal.
However, as I login and use a password, it denies access.

I’ve replace Master user with my name and added a master lock. However this didn’t work anyhow, it keeps denying access.

What’s up with that?

I figured out profiles seem to be different from login?

This page says the default username and password are osmc.

I’ve logged in accordingly.

Also note you should probably install Transmission from the App Store, unless you have a specific reason not to
