Description

I believe my netrc file is set up correctly.
My youtube-dl.conf points to the netrc file.

I dunno why youtube-dl can't access my watchlater playlist. :(

dstftw, duplicate of which? I see a 2018 one, and it says the bug has been fixed in a later version. I have a 2020 version of youtube-dl and i still have this bug.

The same problem is happening to me.

I'm using the .exe for windows version v2020.06.06. I get the same message (WARNING: Unable to log in: HTTP Error 400: Bad Request) providing credentials in command line as well as in configuration file.

I agree with hub2git that it is a new bug.

Regards.

The error persists when switching to another computer.
Adding cookies worked for me.

However, I found it only working when selecting "Http Only" mode on the cookie extractor.
I used https://addons.mozilla.org/en-US/firefox/addon/export-cookies-txt/?src=search on Mozilla Firefox.

Also, make sure you are using the correct password.

With this workaround I still get the HTTP 400 - error, but it proceeds to download my liked videos playlist anyhow. This means youtubedl is accessing my google account to get the job done despite the error.
