This is a simple demonstration of form fields hidden from the user, but will be filled anyways when using the browser form autofill feature, which poses a security risk for users, unaware of giving their information to the website.

Here's the demo in action on the Google Chrome Browser:

It works differently in some other browsers. For example:

• In Safari, it will tell you all the data it is filling into the form, even if it isn't visible to you.

• In Firefox, you have to right click an input field and then select an identity to use. So a Firefox user autofills each field.
