I was getting "fatal: Authentication failed" when pushing to overleaf (online LaTeX collaboration)
I had entered the wrong username in the authentication box, and I couldn't make it appear again. There was no entry for overleaf in Windows Credential Store.
I tried deleting the password entry in the passwd file in the C:\Users\USERNAME\AppData\Local\Atlassian\SourceTree, and it would display the dialog, but I couldn't change the username
The solution was to change the username in the username file in C:\Users\USERNAME\AppData\Local\Atlassian\SourceTree
I hope this helps someone. It would be nice if there was a dialog for this.
