Verification platform

Three verification experiences

Choose V1 for an explicit challenge, V2 for managed step-up, or V3 for a frictionless action score.

  • Version-bound tokens
  • Site and hostname validation
  • Action-aware policy

Verification platform

Abuse controls at the boundary

Layered limits, one-time token consumption, key rotation, and fail-closed replay protection protect verification paths.

  • Replay resistance
  • Credential rotation
  • Bounded retries
