git commit --amend --reset-author

gistfile1.txt

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

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
