Answer by AADProgramming for Remove credentials from Git

For Windows 10, go to below path,

Control Panel\User Accounts\Credential Manager

There will be 2 tabs at this location,

1. Web credentials and 2. Windows credentials.

Click on Windows credentials tab and here you can see your stored github credentials,under "Generic credentials" heading.

You can remove those from here and try and re-clone - it will ask for username/password now as we have just removed the stored credential from the Windows 10 systems
