What is the "Password Lock for WhatsApp Web" extension and how does it work?
This extension provides an added layer of security to WhatsApp Web by obscuring the interface when locked, preventing any content from being viewed. The user must enter and confirm a password on the first use, which will protect all new instances. You can lock all WhatsApp Web instances by clicking the action button (toolbar button) or using a custom keyboard shortcut. The extension offers two protection modes: You can either unlock the application and keep it open, or you can set it to automatically lock after a specified period. Despite the added security, desktop notifications and sound alerts still work as usual.

Where does the extension store my password? Is it safe?
The extension uses a process called "hashing" to store your password. Hashing is a method of taking a plain text password and running it through a mathematical algorithm, which generates a unique, fixed-length string known as the hash. This extension only keeps the hash, and the password itself is not stored, which means that even if someone were to access the stored hash, they would not be able to determine the original password. The extension uses the private storage of your browser to keep this hash and other user preferences. It is important to keep your password safe, as there is no way to unlock the application if you forget it. However, if necessary, you can uninstall the extension to regain access to WhatsApp Web. Instructions on how to protect the browser extension from being removed can be found in later FAQs so that you can ensure that nobody can remove this protection layer without your permission.

How can I access the options for this extension?

Is it possible to set the extension to lock WhatsApp Web when my computer is inactive?
Yes, you can configure the extension to automatically lock all open instances of WhatsApp Web if your computer is not in use for a specific period. This feature is useful to prevent unauthorized access to your WhatsApp Web when you are away from your system. "Idle" refers to the state in which your computer is not being actively used or is not receiving input from the keyboard or mouse. By setting a time limit, the extension will automatically lock your WhatsApp Web, providing an extra layer of security when you're away from your device.
