Security

The API uses JWT for authentication. JWT tokens are provided in the response body of a login request. Include the obtained JWT token in the Authorization header before sending a request. JWT token is required for all handled endpoints except register and login.

In Postman, select Bearer token in Authorization tab In Swagger UI, enter the token in Authorize section

Role-based Access

Users have the role USER. Admins have the roles ADMIN and USER. Passwords are stored in the database table named roles with BCrypt encoding
