PROBLEM TO BE SOLVED: To provide a method suitable for providing a user access to a secure application. SOLUTION: The authentication information necessary to satisfy the authentication requirements of the secure application is stored in an encrypted form. When the user requests access to the secure application, the user is presented at his or her display with a request for authentication. The user must manipulate at least a part of the symbol to respond properly to the authentication request. The user's manipulation of the symbol generate a CodeKey used to decrypt the encrypted stored authentication information into a result. After the result is created, it is provided to the secure application. If the result supports the secure application's authentication requirements (i.e., if the CodeKey has properly decrypted the encrypted stored authentication information), the user is granted access to the secure application.
