Two-Step Authentication that Provides Highly Secure Access to Secure Areas or Resources

Authors: Victor Solovyev

A two-step authentication system and method are provided for secure authentication that implements highly secure access to secure areas or resources with disabling the access when the main passcode is compromised. A user, after successfully passing through the passcode of the first-step verification stage, is asked to input an additional secret and presumably easy memorezible code (a pin, second password), or recognize an image for authentication (from a generated set). If during this second-step the user entered information fails to match the correct secret code, then the system sends signal message on intrusion to the user or other designated authorities through a communication device (e.g., email or telephone message) and the access is disabled immediately or after a few permitted attempts. Such authentication, while providing better security and user experience, does not require the usual practice of disabling the access, when the first-step access required information (such as complex alphanumeric password) is entered with errors in repeated access attempts.
