How to Use curl with Username and Password for Secure API Authentication?

Hey, just wanted to say thanks for all the suggestions! I tried using environment variables, and it worked like a charm. I also looked into `.netrc`, and it seems like a solid option for keeping things secure.

One follow-up question: if I use `.netrc`, how do I handle multiple APIs with different credentials? Do I just add more entries to the file?

Cheers!
