PROBLEM TO BE SOLVED: To provide a method suitable for providing a user access to a secure application. SOLUTION: 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 portion of a symbol to respond properly to the authentication request. The user's manipulation(s) of the symbol(s) generate a CodeKey used to decrypt the encrypted stored authentication information into a result. After the result is created, the result 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 will be granted access to the secure application.
