 The Credential Issuer provides a nonce value in the HTTP response with a 2xx status code and the following parameters included as top-level members in the message body of the HTTP response using the application/json media type:
 
-* `c_nonce`: REQUIRED. String containing a nonce to be used when creating a proof of possession of the key proof (see (#credential-request)).
-* `c_nonce_expires_in`: OPTIONAL. Number denoting the lifetime in seconds of the `c_nonce`. This value serves only as a hint to the Client, indicating how long the Credential Issuer is likely to accept the `c_nonce` as valid.
+* `c_nonce`: REQUIRED. String containing a nonce to be used when creating a proof of possession of the key proof (see (#credential-request)). This value MUST be unpredictable.
 
 Due to the temporal and contextually sensitive nature of the `c_nonce` value, the Credential Issuer MUST make the response uncacheable by adding a `Cache-Control` header field including the value `no-store`.
