Authentication Service
The Authentication Service is a microservice built with Kotlin and Spring Boot that handles user authentication and authorization for the entire microservices architecture. It provides secure access to protected resources across all services.
Key Features
User Authentication: Verifies user identities through username/password, OAuth, or other authentication methods.
Token Management: Issues, validates, and refreshes JWT (JSON Web Tokens) or other authentication tokens.
Authorization: Manages user roles and permissions to control access to resources.
User Registration: Handles the creation of new user accounts.
Password Management: Manages password resets, changes, and security policies.
Integration with Other Services
The Authentication Service integrates with other microservices through:
The authentication-library, which provides common authentication functionality
The spring-boot-starter-authentication, which simplifies integration with Spring Boot applications
RESTful APIs for authentication and user management
Security Measures
Secure password storage using bcrypt or similar hashing algorithms
Protection against common security threats (CSRF, XSS, etc.)
Rate limiting to prevent brute force attacks
Audit logging for security events
