If there is none, binding fails with `no_device_proof`. If getting the proof itself fails, binding fails with that error.\n\n**Why**\n\nAn account can no longer be bound to a device without a proof from that device. If binding fails, the `no_device_proof` error says why.\n\n- Area: Auth\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5"}
