Methods and systems for managing access to a resource by one of a plurality of applications. The method comprises: storing, in a first storage area associated with a first application, a first credential for use in accessing the resource; receiving, at a second application, a message comprising data for determining that the first application stores a validated credential for accessing the resource; sending a request for the validated credential from the second application to the first application; receiving the first credential at the second application from the first application in response to the request sent; and storing the first credential in a second storage area associated with the second application; wherein the message received at the second application is received from a server system, remote from the plurality of applications, which maintains data indicating a subset of the plurality of applications which store respective validated credentials for accessing the resource.

Managing access to resources

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.

Controlling access to a resource via a computing device

Data is stored on a computing device in an encrypted form using a control application. A data access application requests access to the data. It is determined whether the data access application has available a shared encryption key that is available to the control application. If a shared encryption key is available, the shared encryption key is used to encrypt a request for access to the data. If a shared encryption key is not available, a shared encryption key is negotiated with the control application, and the negotiated shared encryption key is used to encrypt the request for access to the data. The control application receives the encrypted request, decrypts the encrypted request using the shared encryption key, and makes the data stored on the computing device in encrypted form available to the data access application in response to the decrypted request.
