Can't login to GitHub from SourceTree anymore : <p>I was able to login up until today when it just stopped working. I'm using a Windows 7 machine. I have 2-factor authentication.</p>

<p>I've tried personal access tokens. I've tried deleting my credentials and re-adding them. I've tried nuking and/or updating credentials in Windows Credentials Manager. I've tried OATH vs Basic authentication. No luck. It just keeps asking me for "Username or email" and "password". (Man, I hate that login prompt now.)</p>

<p>I've tried changing my GitHub password. I've tried authenticating with OAuth (SourceTree says it's connected, but then I get the login screen again).</p>

<p>Can anybody out there give me a list of steps to get back into our repo from SourceTree? I'm blocked now and unable to do work until I get this fixed.</p>

<p>Thanks very much,
  Jeff</p>
