One of the features I, and many users, love about Firefox is the Master Password feature.
Chrome does not have this, and is an important reason I don’t use it.
It requires one to first identify with the master password before auto-fill is allowed,
and has the option to display saved passwords after identifying (not sure about this one, safety-wise, but it has helped me tremendously).
External services offer similar fuctionality, but built-in is nice.
I welcome your feedback on this feature request.
