Stina was the Head of Trust & Safety at Norðurlys , a fast-growing Nordic green energy startup. Her job wasn't just about firewalls and antivirus; it was about the gnawing, 3 AM fear that lived in every CTO’s chest: the key to the kingdom was a password. And passwords were a lie.

Lars held up his keychain. The YubiKey’s gold contact blinked once, innocently. "Sorry," he mumbled. "I won't leave my laptop unlocked again."

And sometimes, that was enough.

On the attacker’s screen, a simple, infuriating message appeared: Access blocked. Security key required.
