Security and convenience are provided by a system, apparatus, method, and computer program product that stores two or more encryption keys that correspond to two or more levels of authentication. The encryption keys may be encrypted and decrypted utilizing an endorsement key and trusted computing techniques. Or the encryption keys may be stored in a secure manner utilizing key protection techniques, such as cryptographic camouflaging. A first encryption key is recovered automatically for the first level of authentication. And input is requested to recover the second encryption key for the second level of authentication.
