How to protect your Google and Facebook accounts with a security key

In late March when I got an unsettling message on my Gmail account: “Warning: Google may have detected government-backed attackers trying to steal your password.”

Google sends them out when it detects a “government-backed attacker” has attempted to hack an account through phishing or malware.

Last time I saw one, I added two-factor authentication to many of my accounts. This time it prompted me to ask: Can I do even better?
