Login problems with GitHub and Two-factor authentication


friday we can not sign in to GitHub anymore with SourceTree. Even the attempt with the Personal access tokens does not work. Problem exists only with the two-factor authentication.

This issue is caused by Sourcetree's embedded Git client using git-credential-manager v1.12, which no longer works with Github since they disabled TLS 1.1 on their site (and didn't bother to tell anyone). Due to this, only the latest version of Git for Windows will work with Github.


To use the latest version:

  • Download and install Git for Windows
  • Open Sourcetree, the go to Options > Git
  • Click the "Use System Git" button
  • Additionally, check "Enable TLS 1.2" under "Network"

Works! after hours of searching for a solution! Thanks!

Thank you, this also worked for me. One small thing that confused me.
I was not able to select the "Use System Git" button, it appeared to be disabled / greyed out .... but as it turned out it was disabled because it was already selected / default

Phew!  I was also able to solve this on the Mac app by clicking "Use System Git" via Sourcetree Preferences > Git  

Hello ,
