Well, during git setup somehow I have accidentally set my password as my e-mail. That was like a week ago, and there are like 20 commits with it.
I tried to change them following this: https://help.github.com/en/articles/changing-author-info#changing-the-git-history-of-your-repository-using-a-script But there is now a copy of every commit that was affected but with the correct e-mail.
This is my personal project, so changing its git history is not that big of a deal.
