Locker is a free browser add-on developed by HTHS Proctor for Chrome users. This add-on brings locked mode functionality to Chrome, without the need for a Chromebook. With Locker, you can enable a secure locked mode on your computer when working on a specific form.

The main feature of Locker is its automatic proctoring capability. When a specific phrase, "This form is locked. Enter your name to confirm," is listed as a paragraph question on the form, Locker takes action and locks your computer. This ensures that only authorized individuals can access and complete the form, providing an additional layer of security.

Locker is a valuable tool for those who need to enforce locked mode on forms without the requirement of a Chromebook. It offers a simple and effective solution to ensure the integrity and confidentiality of sensitive information. With Locker, you can have peace of mind knowing that your forms are protected and only accessible by authorized users.
