One feature of 1Password (and other password managers with browser integration) that has saved me at least twice by now: The browser extensions will autofill only for matching domains. If autofill doesn't work on a site I have credentials in 1Password for, chances are it's a phishing attack. That's a last line of defence against well-crafted phishing attacks that I wouldn't want to give up.
