I want to know how to encrypt Google Chrome passwords so that no one can show it. There is no option for a master password to encrypt passwords saved on Chrome browser, and I want to make it more secure

To install keepass2 you can use
sudo apt-get install keepass2 keepass2-plugin-keepasshttp keepass2-plugin-rpc keepass2-plugin-application-menu keepass2-plugin-application-indicator
ChromeIPass is installed from the chrome webstore:
