How to Implement Multi-Device Authentication System with FastAPI, Redis, and JWT | HackerNoon
Briefly

Using JWT for authentication in a stateless application ensures that we can efficiently manage user sessions across multiple devices without the overhead of server memory.
The inclusion of only essential information like session_id and username in the JWT prevents the token from becoming too large while still allowing for effective request authorization.
By utilizing Redis, we can store device-specific data and manage user sessions seamlessly, allowing users to interact with our application from various devices.
The combination of Redis and JWT offers a scalable solution for managing authentication, enabling users to log in from multiple devices with ease.
