Similar to Bitwarden and other managers, it would be nice for Proton Pass to automatically lock whenever you close your browser, put your computer to sleep, restart your computer, etc. You would need a password (either your master password or a secondary password) to unlock Pass once you reopen your browser.

I'm aware that this feature already somewhat exists when you create either a pin or a secondary password, but Pass will only lock after a set timer countdown rather than closing and reopening the browser.
