How to clear username and email in Git

As a very popular version control tool, Git is loved by more and more developers. However, when using Git to upload code, many developers will encounter a problem, that is, if the user name and email are incorrectly set when submitting the code, then this information will be permanently recorded in the Git history. And it cannot be modified or deleted. This may not be a problem for some developers who use personal computers to develop, but if they are developed on public computers or commercial equipment, it will cause the risk of information leakage. Therefore, this article will explain how to clear your username and email in Git.

Step1: Check the global configuration of Git

First, open the terminal and enter the following command to view the global configuration information of Git:

git config --list --global

git config --global --unset user.name
git config --global --unset user.email

After resetting, you can correctly record the developer's information when submitting code when using Git.
