git commit --amend --reset-author

Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

that's normal -- it means that when git does the commit for you, it allows you to edit the commit message, by default using the Vi editor, which works so that you can exit it by doing :wq

Doing the global change wasn't enough for me - I had to do git config user.name "..." and git config user.email "..." before trying to amend.

There is potentially two user.name values set ... One at the --global config and one on the local repository.
If you git config --list the output will have multiple of the same parameters ... the last one in the list is the one used for your current repo.

I clone a repo from account 1 using account 2, after making some changes, i want to push the changes.
But account 2 was denied by remote account 1. So i config the account 1 as the local setting under working directory and ran the reset-author command. After all this, when i commit. It still use account 2 and was denied.

You can add --no-edit to avoid the editor
