AI approvals
Sign financial transfers, healthcare consent, and agent actions with explicit human proof.
1.2 second authorization
KEYRA turns intent into cryptographic proof — without pushing you into an app-switch obstacle course.

Challenge lifecycle
Every high-trust action follows the same human-in-the-loop pattern — whether the request comes from an app, an AI agent, or a physical lock.
01 · Request
An app, AI agent, or lock issues a cryptographic challenge — never a password field.
02 · Verify
You touch KEYRA ONE. Biometric proof is checked locally in milliseconds.
03 · Attest
The secure element signs a response bound to the challenge — no replay possible.
04 · Sign
The relying party receives hardware-rooted proof that a human authorized the action.
Use cases
