When you develop an application, it has to communicate with other services — on your infrastructure, cloud infrastructure services, or third-party applications. Of course, you don’t want just anyone to masquerade as you, so you use secrets like SSH keys or API tokens to make the communication secure.

And, if the secret is for something billable (like public cloud infrastructure), they can cost you a lot of money.
