If an adversary is able to get hold of a key proof defined in (#proof_types), the adversary could get a Credential issued that is bound to a key pair controlled by the victim.

Note: For the attacker to be able to present to the Verifier a Credential bound to a replayed Key Proof, the attacker also needs to obtain the victim's private key. To limit this, servers are RECOMMENDED to check how the Wallet protects the private keys, using mechanisms such as Key Based Client Authentication defined in [@I-D.looker-oauth-attestation-based-client-auth].

`nonce` parameter is the primary countermeasure against key proof replay. To further narrow down the attack vector, the Credential Issuer SHOULD bind a unique `nonce` parameter to the respective Access Token.
