Supplying per-site login credentials in config file

Description

I'm using youtube-dl in tandem with SMPlayer to watch videos from multiple websites (YouTube, BitChute, mgtow.tv, dlive etc.) but since my login credentials aren't the same on all sites simply putting -u USERNAME -p PASSWORD in the config file will not work. SMPlayer itself lacks the feature to provide login/password to youtube-dl on its own, and just passing the password as a command line parameter is a security risk anyway cause it's visible with ps aux. Using a cookies.txt is also not an option because only YouTube has "permanent" login cookies so I'd have to re-generate it way too frequently. This feature would help with age restrictions, private videos etc.

I tested it with private videos of mine following what you linked but to no avail.

my .netrc file:

machine youtube login csehszlovakze@gmail.com password <REDACTED>
machine bitchute login csehszlovakze password <REDACTED>

YouTube:

While BitChute throws a 404 error while not logged in, it's just a private video:

I also tried changing the username to email but the result is the same.

logging in to youtube is definetely broken currently (#26196). bitchute extractor has never supported logging in.

Thanks for the heads up.
