摘要： A system includes a memory and a processor. The memory is operable to store a credential verifier associated with a user account and a counter. The processor is coupled to the memory and the memory includes executable instructions that cause the system to receive a first authentication attempt and increment the counter if validation of the first authentication attempt against the credential verifier fails. The instructions also cause the system to receive a second authentication attempt and increment the counter only if validation of the second authentication attempt against the credential verifier fails and the second authentication attempt is distinct from the first authentication attempt.
