There are many ways to avoid putting credentials into your repository in the first place, and you should try to implement as many as you can; however there’s always the chance some sensitive information may sneak in. You should also consider regularly auditing your repos, making use of tools like GitRob or truffleHog, both of which scan through your codebase, searching for sensitive information via pattern matching.
