Creating a Secure Login and Signup Process for Web Applications

Let’s continue our exploration of advanced techniques to make our web applications look professional and work well.

In this chapter, we are going to learn how to implement a login and signup page made with Secure Hash Algorithm 256 (SHA-256) encryption and connected to a database in a secure and user-friendly way. By adopting this approach, we will be able to authenticate our web app users and store their credentials permanently. The login and signup page typically consists of a form where users can enter their username and password to access the web application. When a user logs in, their credentials are hashed using SHA-256 and compared to the stored hash in the database (in this context, we are using SQLite3). If the hashes match, the user is authenticated and granted access to the application. The signup page allows new users to create an account by entering their desired username and password.
