Remove credentials from Git

Question

I\'m working with several repositories, but lately I was just working in our internal one and all was great.

Answer 1

I found something that worked for me. When I wrote my comment to the OP I had failed to check the system config file:

line. I unset it with

git config --system --unset credential.helper

and now the credentials are forgotten.
