Thank you bro : )

Thank you!

@bgromov , Newname is our github id or actual name?

Nice! This even keeps old timestamps!
To push to a remote afterwards, a --force is needed.

git push --force --tags origin 'refs/heads/main'
# or
git push --force

Thanks. To update only your commits and not all ( even if not yours):

#!/bin/sh

git filter-branch -f --env-filter '
OLD_EMAIL="xxxxxxxxxxxxxxxxxxxxxxxxxx"
CORRECT_NAME="zzzzzzzzzzzzzzzzz"
CORRECT_EMAIL="yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_COMMITTER_NAME="$CORRECT_NAME"
    export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi
if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_AUTHOR_NAME="$CORRECT_NAME"
    export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
'  HEAD

Thank you so much!
