I was having problems getting SourceTree to login to Stash after changing the password. After a lot of trouble I just fully deleted the password variables, deleted SourceTree, deleted all file locations on my machine and after restarting the machine reinstalled SourceTree. Now it won't let me clone the Stash project to put it back into SourceTree. It still says that I have a fatal authentication error. When I look the password variables have returned. I think it still uses the old password but I can't convince it to use the new one. It won't prompt me for the new password.
