A system and associated method for authorizing, or withholding authorization of, user access to a selected computer application or other resource, based on the user's response to one or more user authentication tests. If the user satisfies one or more authentication tests but satisfies less than all the tests, the system optionally allows the user access to a selected subset of the resource. Alternatively, the user loses access to a selected subset of the application for each test not satisfied by the user. An authentication test or its associated weight may change at a selected time, and the selected time may be determined with reference to a time at which the resource changes.
