Remove credentials from Git

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

Today I had to commit and push code into other one, but I'm having some troubles.

$ git push appharbor master
error: The requested URL returned error: 403 while accessing https://gavekortet@appharbor.com/mitivo.git/info/refs?service=git-receive-pack
fatal: HTTP request failed

There is nothing I can do, that would bring the password entry again.

How can I reset the credentials on my system so Git will ask me for the password of that repository?

I have tried:

• git config --global --unset core.askpass

in order to unset the password

• git config credential.helper 'cache --timeout=1'

in order to avoid credentials cache...

Nothing seems to work; does anyone have a better idea?

If this problem comes on a Windows machine, do the following.

• Go to Credential Manager

  • in Czech, it is called: Správce pověření
  • in Dutch, it is called: Referentiebeheer
  • in French, it is called: Gestionnaire d'identification
  • in German, it is called: Anmeldeinformationsverwaltung
  • in Italian, it is called: Gestione credenziali
  • in Norwegian, it is called: Legitimasjonsbehandling
  • in Polish, it is called: Menedżer poświadczeń
  • in Portuguese, it is called: Gerenciador de Credenciais
  • in Russian, it is called: Диспетчер учётных данных
  • in Spanish, it is called: Administrador de credenciales

  

• Go to Windows Credentials

• Delete the entries under Generic Credentials

  

• Try connecting again. This time, it should prompt you for the correct username and password.
