How to change Author name in Git [duplicate]

Question

I've changed my username in GitHub. I've made few commits to my Git and entered the command >git log to see my commits. In the Author section, it is still showing my previous username. How do I change/update my current username on Git? Also it should reflect in Author section after making commit.

> git log
commit commitId (HEAD -> master)
Author: **My previous username** <My email id>
