Subject: Resetting git account from system completely

Hey! there, Actually the issue is that I've installed git on other laptop and set up my git account using my own git username, mail and password, and start using remote github for cloning, pushing etc. But now I want to reset my all the setting from that system, so that when someone try to using git on that laptop they won't be able to manipulate my git, github repos, It will prompt for them username and password. I've tried every possible way from deleting credentials from windows credential manager and git config --global --unset credential.helper renaming and deleting .gitconfig file changing PAT on github resetting password and tried chatGpt's steps, gemini and what not. Could you provide me step-to-step guide to resolve this issue? Please help me to resolve this. Any advice appreciated. Hopping response from git community. operating system using = window 11 Thank you
