I am getting Bad authnetication error

[d78ui98]

[ERROR] Bad authentication, login or password incorrect ('server says: BadAuthentication')

[ouaguid]

The email address used (or its password) is wrong, check it again by trying to connect to your Gmail account (via a browser).

Hello ouaguid. Thanks for the reply.
The email and password used were right. Was still not able to connect.
But now I am able to fix this issue.
Thank you anyway :)

I am also getting a "BadAuthentication" response from the server. I have verified the password and email is correct and attempted to unlock the account here "https://accounts.google.com/b/0/DisplayUnlockCaptcha". I have also tried multiple different accounts. @d78ui98 How did you end up getting auth working again?

Turns out to be the version of requests not playing nice with the lib. I downgraded from requests version 2.25.1 to 2.20.0 and now I can sign in. I hope that helps someone else having the same issue.

I havn't tracked all the packet but the Raccoon is working well.
I am using the GSFID and token from it.

I found the problem. it was proxy in my case.

I found the a possible explanation: the auth header different for different auth type:
if you use token, the auth header sould be in googleplay.py#L144 :
headers["Authorization"] = "Bearer %s" % self.authSubToken

But if you use username/password (i use "app password"), the auth header works this:
headers["Authorization"] = "GoogleLogin auth=%s" % self.authSubToken

The reason for why you have to do this is that the Auth API does TLS fingerprinting, so the client has to have a specific TLS signature otherwise the server rejects the requests.

I found the problem. it was proxy in my case.

For this same reason, the auth API cannot be used with most proxies because the proxy messes with the TLS fingerprint. I did some experimentation with the fingerprinting and found a valid fingerprint that at least for me has worked reliably:

Here is a quick and dirty patch for the Bad Authentication issue: gentoolinux@6e4c7a4
This solves the issue for me but some advanced programmer should check this before merging it.
My patch is inspired by simon-weber/gpsoauth@6a52a38

Racoon also returned "Bad authentication" error

I downgraded urllib3<1.26.0 (which is same as downgrading requests) and there is no more BadAuthentication. I think there are some ssl errors causing this.

If you stick to urllib3>1.26.0, you can try #145. I think it is already fixed.

My fork works for me. I also uploaded it to pypi.
