LazySec is a free Chrome extension developed by Agustín Tobio Corneu. It falls under the category of Browsers, specifically Add-ons & Tools. This simple tool is designed for software testers but can be used by anyone. Its main purpose is to assist in testing Lazy Security implementations in the UI.

The extension offers two main features. First, it unlocks all elements of a webpage by removing attributes such as "disabled," "readonly," "maxlength," and "required" related to form validations. This allows users to write on forbidden fields or input forbidden content. Second, it makes visible elements that are hidden by attributes or styles such as "display:none," "type=hidden," and "visibility=hidden."

LazySec eliminates the need to open the console or inspect the page's DOM, making it more accessible for average users. It aims to challenge the notion that unlocking webpage elements requires specialized knowledge. With LazySec, anyone can easily perform these actions.

It is important to note that LazySec is intended for testing purposes and should not be used maliciously. The extension provides a convenient way for testers to enable fields and reveal hidden objects without manually modifying the HTML. By using LazySec, web applications' security and validations can be implemented more effectively.
