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**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

Following are advantages for using temporary credentials:

- Eliminates the need to embed long-term credentials with an application.
- Eliminates the need to provide access to buckets and objects without having to define static credentials.
