title: Storing API Keys / Connection String in private Git Repo
body: <p>I'm wokring on a solo project and have added my connection string and a couple of API keys to a private github repo.</p>
  
  <p>I'm thinking it's private so it must be safe but I don't know if this is good practice? Recently, I've created environment variables and keep the config on my local pc instead. However, it's still there in Git history.</p>
  
  <p>Should I be bothered to remove this or am I just being paranoid?</p>
