Proving it's really you when you sign in is usually a small chore: a code copied from one screen to another, a fiddle at the worst possible moment. Kaito shrinks it to a single tap. A prompt appears on your wrist, you approve it, and you're in.
It rides along on the devices you already wear and carry — phone, watch, a glance at a widget — and keeps a set of paper-safe recovery codes for the day a device goes missing. Security that gets out of the way is security people actually use.
