Lock My Chrome is a Chrome extension that enhances security by requiring a password to access the browser when this feature is enabled. Once installed, the extension ensures that Chrome is protected by a password, preventing unauthorized access to any window. Upon the initial usage post-installation, users are prompted to set a password for accessing Chrome, which becomes necessary for subsequent logins.

In case of computer inactivity or lockout, users must log in again, and all tabs are shielded by a blank layer until the password is re-entered. It's important to note that the password cannot be changed until the next version release, although users can reset it by uninstalling and reinstalling the extension.
