Abstract: Embodiments described herein enable a user to bypass the use of one-time keys or account recovery codes by providing techniques for accessory assisted account recovery. In various embodiments, accessory assisted account recovery makes use of an accessory device of a user, where the accessory device can be any device having a secure processor, cryptographic engine, public key accelerator, or is otherwise able to accelerate cryptographic operations or perform cryptographic operations in a secure execution environment. An account recovery key can be split into multiple portions. At least one portion of the recovery key is then encrypted. The accessory device is then configured to be uniquely capable of decrypting the encrypted portion of an account recovery key.
