How can I implement user authentication and authorization using token-based approach in my web application?
To implement user authentication and authorization using a token-based approach in your web application, you can follow the steps below:
1. Choose a token-based authentication framework: There are several popular frameworks like JSON Web Tokens (JWT) and OAuth that provide secure token-based authentication.
2. Generate and store tokens: When a user logs in, generate a unique token and store it in a secure database or cache.
3. Authenticate and authorize requests: With each request, verify the token’s validity and assign appropriate permissions based on the user’s role.
4. Secure token transmission: Use HTTPS to encrypt the token during transmission to prevent tampering.
By following these steps, you can ensure secure user authentication and authorization in your web application using a token-based approach.
