All of us have probably heard of the term 'autofill', which has been incorporated into the function of browsers.
A system that automatically fills out your previously saved login information for a web application streamlines the login procedure for web applications by automatically entering your previously saved credentials.
The majority of widely used browsers, such as Firefox, Chrome, Edge, Opera, and Internet Explorer, have the autofill feature switched on by default by default, which is why this option is so widely used. Unfortunately, there are some instances when it is impossible to disable the functionality completely.
In Chromium-based browsers such as Chrome and Edge, for example, passwords cannot be blocked from auto-filling; a feature that cannot be disabled, because the feature is part and parcel of the browser.
You can only prevent autofill from occurring on such browsers by never saving your credentials. The prevention of an XSS attack is something that needs to be treated very carefully. Now let's talk about how it all works.
In the event that your browser encounters a 'password' input tag, it will automatically fill it in with the password that you specified.
XSS attacks allow the creation of password fields anywhere on the page in order to wait for the browser to fill them in before fetching and sending them to the server, as long as the password field appears to be automatically filled up by the browser.
The primary objective is to increase awareness of this attack vector as well as inform users of the adverse consequences of utilizing autofill. Autofill is usually enabled by default in most browsers.
Therefore, if you wish to prevent such attacks from occurring, either do not use this function or do not remember your password at all.
Don't save your credit card numbers or other key passwords into your browser. Particularly if you use the site for shopping or banking.
