Sourcetree remote: Invalid username or password

Question

Im trying to push to github with sourcetree but get the following error:

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin

Answer 1

In my case, this happened on one of my two computers after I switched to OAuth on GitHub. The error message was referring to git-credential-manager.exe, which is located in AppData\Local\Atlassian\SourceTree\git_extras. I noticed that the version on my working machine is from 2018, whereas the one on the non-working machine is from 2017. Both run the newest version of SourceTree (3.0.17). This is what I did to get it to work:

1. Uninstall SourceTree
2. Since this did not remove AppData\Local\Atlassian\SourceTree, I deleted that entire directory manually
3. Updated git to the newest version (neat: >git update-git-for-windows) - probably not necessary but a good idea anyway
4. Re-installed SourceTree
5. Added existing local repos
6. Fetch - and finally, after entering username and password (twice, if memory serves), I get asked for the OAuth token. Yipee!

Surprisingly, AppData\Local\Atlassian\SourceTree\git_extras was created, but is now empty...
