Secure passcode entry

Methods and devices for presenting a secure passcode system to a user are disclosed. The methods and devices may include a security prompt displayed to a user, wherein the prompt comprises a sequence of passcode elements. The passcode elements may comprise both response-eligible and response-ineligible passcode elements. The security prompt may receive an input from a user and determine whether the response is correct. A correct response may include each of the response-eligible passcode elements and none of the response-ineligible passcode elements. If a correct response is received, the security prompt may permit further access to a function.
