Abstract
The present invention provides methods of, and computer programs and systems for, controlling access to a resource via a computing device configured to perform a method that enables new encrypted versions of a key, encrypted with code values in a sequence of code values that are valid at a future time, to be provided and made available for future performance of the method. This in turn enables a method of user verification that does not require access to a remote server in order to provide one-time passcode verification, and so provides an offline one-tome passcode authentication method that is self-sustaining.
