It's very annoying when you write some code at work, say, reproducible cases for OSS issues, but then commit those under work-related credentials and push on GH

To avoid this from happening, I've wrote such a pre-push hook and put it into .git-templates folder (see recipe on global hooks)

#!/bin/bash -e
#
# Git pre-push hook that blocks push if commits are authored or committed using non-personal credentials
#
# Source: https://github.com/git/git/blob/87c86dd14abe8db7d00b0df5661ef8cf147a72a3/templates/hooks--pre-push.sample
