How to create auto sign up script for a website

What if you want to login to a website by filling in username/email and password automatically?

Well, there is a simple solution for that. This solution works for a lot of websites that have a login and password field inside a form.

An HTML auto login demo page is a web page that demonstrates how to create an HTML form that allows users to log in automatically, without having to enter their username and password each time they visit the website.

The form uses HTML and JavaScript to save the user’s login credentials to the browser’s local storage, which is a feature that allows web applications to store data on the user’s device.


The Demo The page typically includes a login form that prompts the user for their username and password, and a button that allows them to save their credentials. Once the user has saved their credentials, the form will automatically fill in their login information the next time they visit the website.

The demo page is often used as a learning resource for web developers who want to add login functionality to their own websites. It can be customized and modified to suit the specific requirements of different websites, and it is a useful tool to improve user experience and increase engagement in web applications.

Here is a home page of simple session (Crunchify-LoginPage. html) in which I need to provide email and password.

So you can fill in the above fields automatically, just create a Crunchify sample file. html on your desktop or in a convenient location and place it below the content.

Crunchify.html Code File

Crunchify Login Page function loginForm () { document.myform.submit(); document.myform.action = “”; } body { background image: url(‘’); }

And that’s it. Just double click on the above file and you are good to go.

This is what will happen internally:

  • When you open the Crunchify.html file, its dedicated page will open internally Crunchify-LoginPage.html
  • Internally it will pass your provided email and password into the Crunchify.html file
  • Once submitted, it will proceed to the Success.html page

This is a very basic HTML tip, but sometimes it saves a lot of time for repeated login activity.

Here is a frequently used login page for this example:

Example of Python :

This is a complete example of auto login to a website using the HTTP POST method in Python:

import requests # Set the target URL for the home page of session url = “https://www” # Define the payload to be sent with the POST request, including username and password payload = { “username”: “user”, “password “: “pass” } # Send a POST request to the URL with the payload response = requests. post(url, data = payload) # Check the response status code to determine if the login was successful if the response.status_code == 200: print(“Login Success”) else: print(“Login Failed”)

Please note that the above code is just an example, and the exact details may vary by website which you are trying to log in to.

You may need to modify the URL, payload, or other aspects of the code to match the specific requirements of the website.

In addition, some websites may use additional security measures, such as anti-CSRF tokens or captchas, which should be handled in code.
