Abstract: Systems and methods for use in enhancing the security of a system, network, device, data storage element, software application, document, account, data, structure or building. Specifically, the invention is directed to a method of determining a password time-to-live (TTL) value for a password created by a user. In one embodiment, the TTL is extended relative to a baseline or default value if the user creates a password that is expected to produce an increased level of security. Such a password may be longer, include a certain combination of characters, be judged as more complex by an appropriate algorithm, rule or heuristic, or be considered as more secure or desirable by using any other suitable measure or criteria.
