Sometimes - no matter how careful we try to be - we might inadvertently expose sensitive data on GitHub. Unfortunately, it is not as easy as you might think to remove this data again.
Say that you mistakenly commit a file containing sensitive data to your GitHub repository. Simply removing the file from the repository, or indeed deleting the entire repository, will not fix the problem, as…
“commits may still be accessible in any clones or forks of your repository, directly via their SHA-1 hashes in cached views on GitHub, and through any pull requests that reference them” - GitHub Docs: Removing sensitive data from a repository
Luckily, there are ways to fix these types of mistakes.
