In this video we will learn step by step how to implement FastAPI JWT token authentication with a MySQL database using the Tortoise ORM library.

You have extensive knowledge and implement FastAPI dependency injection methods and use JWT web access tokens to authenticate users.

We will create a JWT access token and a JWT refresh token, but there is a more secure way to implement this JWT with refresh token.

JWT Refresh Token: This is a unique token used to obtain additional access tokens. This allows you to have short-lived access tokens without having to re-acquire credentials every time a token expires.

This refresh JWT token is stored in the MySQL user table in my case, but can also be stored in in-memory databases such as the Redis database for enhanced security mechanisms.

Since access tokens are not valid for a long period of time for security reasons, a refresh token helps re-authenticate a user without credentials.

This JWT refresh token is never exposed to the client-side JavaScript. Even if our access token is compromised, it will expire in no time. Therefore, we send two tokens instead of one, an access token and a refresh token.
