What are different Authentication options available in Servlets.
Answer / Dharmendra Kumar Verma
There are several authentication methods available in Java EE Servlets:n
1. Basic Authentication: A simple method where the client sends a base64-encoded username and password in every request.
2. Digest Authentication: Improves upon basic authentication by providing MD5-based hashing and server challenge responses to prevent passwords from being sent unencrypted.
3. Form-Based Authentication: Uses HTML forms for login, often with sessions for managing user state.
4. Custom Authentication: Allows you to implement your own authentication logic using filters, servlets, or other mechanisms.
