Store keys in environment variables

[xeroxzen]

To enhance security and maintainability, we need to store sensitive information such as API keys, database credentials, and other configuration secrets in environment variables instead of hardcoding them in the codebase.

@xeroxzen good call. Do you have specific hardcoded secrets in mind?

[xeroxzen]

@terrameijar the one in the settings.py file or it's not important. Can't we use something like decouple or env variables to have it hidden?

[terrameijar]

@xeroxzen we can and we should! Please create a PR for it.
