In most web applications, users are identified by a unique identifier such as a username or email address. Typically, in a Flask application, you can use a database to store user information, such as usernames, email addresses, and hashed passwords.
When a user attempts to log in, the entered credentials (username and password) are compared to the information stored in the database. If the entered credentials match, the user is authenticated, and a session is created for that user. In Flask, you can use the built-in session object to store and retrieve user information.
By using sessions, you can easily identify users in a Flask web application and retrieve information about them. However, it’s important to note that sessions are vulnerable to session hijacking attacks. So, it’s essential to use secure session management techniques such as regenerating session IDs after login and using secure cookies.
