NYX Unused configuration entry: password

if i run nxy as root(sudo) i do not need to give it a password it is not asking for password interactively for local tor node. but it does warn, it is no good practice.

[NYX_NOTICE] Nyx is currently running with root permissions. This isn't a good
   idea, nor should it be necessary.

if i follow this advise and run it as usr. i need provide controller password. according to [documentation(https://nyx.torproject.org/index.html#configuration)]

i added appended line to

~/.nyx/config

password Torcontrollerpassword

When running nxy without root it still prompt me again for password:

nyx --interface 127.0.0.1:9901 --config ~/.nyx/config
Tor controller password: 

if i provide it the nyx log welcomes me with telling me password config unused :(

[NYX_NOTICE] Unused configuration entry: password

excuse me if im missing something, but i cant see why the config does not apply.
