Spring Boot Security Form-Based Authentication

In this Spring Security tutorial, we will learn how to use Spring Security’s built-in Form-Based Authentication. Spring Security provides support for username and password authentication through an HTML form, making it a user-friendly option for securing web applications.

Form-Based Authentication Overview

Form-based authentication uses standard HTML form fields (login form) to pass the username and password values to the server via a POST request. The server validates the provided credentials and creates a session tied to a unique token stored in a cookie. This token is passed between the client and the server on each HTTP request. If the cookie is invalid or the user logs out, the server redirects to the login page.

Key Points:

• Form-based authentication uses HTML forms to collect user credentials.
• The server validates credentials and creates a session token.
• The session token is stored in a cookie and used for subsequent requests.
• If the session token is invalid, the user is redirected to the login page.
