How to remove git push permission?

Question

How can I remove the permission of git push?

I've tried reinstalling git and deleting .ssh folder and .gitconfig file on my windows machine.

But I still find I'm able to git push to my repository on github.

The reason I want to do this is because the laptop I'm using now will be given to another coworker in my company after a few days.

This is what I get now:

git push
Everything up-to-date

I want it to be:

git push 
Permission denied (publickey).

It seems that the public key stored on github is not used after I type git push.

Are my github account and password stored somewhere in the laptop?

The following is the output of git config --list --show-origin

Maybe I can find some clues from credential.helper=manager.

What is your repository? Do you work with github, gerrit or something else? Can you paste error which you've get from the server? — grundic, May 12 '17 at 09:07
Go to your profile settings on GitHub -> SSH and GPG keys, and delete the key for the machine you want to unpair. — medik, May 12 '17 at 09:11
Update: delete all the keys and see what happens, you're not using them anyway. Are you signed in with the same creds on web and cli? — medik, May 12 '17 at 09:19
I've cleared all the credentials on my browser. I don't know to sign in with CLI. — Brian, May 12 '17 at 09:21
Do you find a credential-helper here: `git config --list --show-origin`? Perhaps have a look [here](http://stackoverflow.com/a/15382950/5784831) — Christoph, May 12 '17 at 09:38
@Christoph, Thank you. The credential is removed after I reboot the laptop. — Brian, May 12 '17 at 09:47

The line file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig" credential.helper=manager tells you that a credentail manager is used.

You can see the different levels of config files in the output of git config --list --show-origin:

file:"C:\\ProgramData/Git/config" --> global, user specific
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig" --> system
file:.git/config --> local, user specific

From the documentation here

$(prefix)/etc/gitconfig
System-wide configuration file.
$XDG_CONFIG_HOME/git/config
Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.
~/.gitconfig
User-specific configuration file. Also called "global" configuration file.
$GIT_DIR/config
Repository specific configuration file.

Important: Local settings always overwrite less local settings
