 * ## Domain Patterns
 *
 * Pinning is per-hostname and/or per-wildcard pattern. To pin both `publicobject.com` and
 * `www.publicobject.com` you must configure both hostnames. Or you may use patterns to match
 * sets of related domain names. The following forms are permitted:
 *
 *  * **Full domain name**: you may pin an exact domain name like `www.publicobject.com`. It won't

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**.
