Design signup and login service
Design a User Authentication Service
Design a fundamental authentication service that facilitates user sign-up and login using an email and password. This service must be implemented without relying on external, third-party authentication providers like OAuth. While the initial design should not prioritize extreme traffic scaling, it must feature a clean API and a well-structured database schema.
Your comprehensive design should address the following key areas:
- Core Requirements: Outline the essential functionalities for both user registration and login processes.
- API Design: Define the API endpoints, including the expected request payloads and response structures for each operation.
- Database Schema: Detail the necessary database tables and their critical fields to support user accounts and authentication.
- Password Security: Explain the secure methods for storing user passwords.
- Login State Management: Describe how a user's authenticated state is maintained after a successful login.
- Validation and Error Handling: Cover basic input validation rules and how various failure cases are handled and communicated.
