On Netflix or shop at Amazon, or when logged into some website, we can see the "remember me" button. Based upon your search, it saves your personal information for recommending products. In a database storing the personalized info of every user is time-consuming. We keep a site's cookies in the user's browser. When visiting a website, cookies save files on your computer or mobile device. 

Flask uses built-in cookie functionality to store session cookies and makes them available to our viewers. This allows the ability to remember the state of a user between browser sessions, such as the ability to remember a logout state or user's preferences. A request object is a powerful tool in Flask. It makes all sorts of advanced web requests. For accessing the request object, the Flask provides a convenient wrapper. This object represents the current HTTP request. The response object of Flask is cookies. With the make_response()method, we must initialize a response object and then attach the cookie key. This has done by the set_cookie() command (value pair to this object).  

A cookie also stores its expiry time, path, and the main name of the site. Cookies are set on the response in the Flask object.SECRET_KEY: Flask "secret keys" store sensitive user data, such as passwords. To get the response object from the view function, use the make_response() function. Using the set_cookie() function, the cookies are stored. It is easy to read back cookies. The HTML file stores the code for getting buttons, login or logout messages, and input text areas. If the login details are correct, the corresponding message will be displayed. Otherwise, it shows 'wrong username or password' or 'danger.'
