I changed my Windows password and now GIT would fail with authentication error, and even doing 2 pull in a row with git pull -v
would not prompt for the new password.
It was really hard to find the Windows credential manager since not only do I have Windows 10, but also it's a French language version.
I finally found on this page I could access it by using:
rundll32.exe keymgr.dll,KRShowKeyMgr
and I double-clicked on the git:http:
line to enter the right password and I was then able to pull and push to the repository.
I hope this helps someone else.
I'd still like to understand why it's not asking me for the new password anymore - it used to ask for it the first 2 months after I got my Windows 10 PC (I change password every month)
