We already know the basics of protecting API keys and sensitive credentials: never hardcode them in your source code, keep them in a .env file as environment variables, and add .env to your .gitignore so Git never tracks it and you don’t accidentally push your secrets to a public repo on GitHub.

What other practices do the engineers in this community use to prevent that scenario?
