Support Youtube/Google one-touch authentication with Android

[hanxue]

When using 2FA to login to Youtube, there is either HTTP Error 500: Internal Server Error or HTTP Error 402.

I suspect it is because Google accounts with an active Android device allow the Android device to authorize sign in request, and 2FA is not required. This is what appears on my Android device:

Could youtube-dl support this one-click sign on for Android when available, and fall back to TOTP/2FA only when it is not available?

Make sure you are using the latest version: run youtube-dl --version and ensure your version is

2FA support seems to be broken altogether, it doesn't work whether I use one-touch authorization or enter the TOTP code... The only way it works right now is by using --cookies.

Also, you may want to make the image smaller. Replace it with this:

Is 2FA still broken? You can stop google sending the prompt to your phone by disconnecting it from the internet. It will fall back to the normal authenticator codes but they don't seem to be working either.

No, 2FA is still not working with the latest version of youtube-dl as of time of this response, 2018.05.18

Note the HTTP error

WARNING: Unable to submit TFA code: HTTP Error 400: Bad Request

Download still works though, just that I think authentication did not go through, and --mark-watched does not work. I check my YouTube history and that video does not appear.

I have uploaded the dump files for YouTube / Google sign in at https://gist.github.com/hanxue/f5b62e6e940ab0e03a3cc60e5f130dd5

Using a browser, going to https://accounts.google.com/ServiceLogin, which is the url used by YoutubeBaseInfoExtractor, redirects me to https://accounts.google.com/signin/v2/identifier?flowName=GlifWebSignIn&flowEntry=ServiceLogin.

Perhaps youtube-dl is using v1 signin which doesn't support 2FA anymore? I don't know how to test this as I can't access the signin page that youtube-dl seems to use through a browser.

Another thing: this problem seems to have moved away from the original subject of this issue. I think there are a few issues open that are related but perhaps we should make a new one purely about 2FA not working?

[hanxue]

The Android one-touch authentication is one of the few forms of 2FA supported by Google. If we are talking about 2FA, it could be OTP authenticator code, or code via phone/SMS. I am happy to expand the scope of this issue to cover all Google 2FA, not just Android one-touch authentication

[blimmo]

From the source:
https://github.com/rg3/youtube-dl/blob/504f20dd302189db2cfe1cb5ee9a622c39ee693c/youtube_dl/extractor/youtube.py#L202

It seems that the authenticator app codes are supposed to be supported while other forms of 2FA (such as the one-touch authentication) aren't yet.

This is why I'm suggesting splitting the issue into one for the bug preventing the existing 2FA support working and one for the request for one-touch support
