# Security - First Steps { #security-first-steps }

Let's imagine that you have your **backend** API in some domain.

And you have a **frontend** in another domain or in a different path of the same domain (or in a mobile application).

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

- For instructions on using KES for encrypting the MinIO backend, follow the [KMS Quick Start](https://github.com/minio/minio/tree/master/docs/kms). The SSE-S3 configuration setup also supports MinIO KMS backend encryption.

## FAQ

> Why is this change needed?

Before, there were two separate mechanisms - S3 objects got encrypted using a KMS,

You could easily use a search engine or video platform to find many resources related to FastAPI.

/// info

Before, this page used to list links to external articles.

But now that FastAPI is the backend framework with the most GitHub stars across languages, and the most starred and used framework in Python, it no longer makes sense to attempt to list all articles written about it.
