I am on mac OS unlike this post:
I have password conf
None of the above solutions worked for me and I don't have admin rights on my laptop, but they eventually led me to the git tools credential storage doc :
My setup Windows 10 | git version 2.18.0.windows.1 | Clone through HTTPS link
This solution works if you use wincred as credential helper :
> git config --global credential.helper
wincred
Changing the helper to "cache" should do the trick, as it will ask you to provide your credentials again. To set it to cache, just type :
> git config --global credential.helper cache
Check your update is active:
> git config --global credential.helper
cache
You should now be able to clone / pull / fetch as before.
