Abstract
A method of device authentication comprises receiving a password into an application of a user device; transmitting verification information of the password from the application to an authentication device; verifying, by the authentication device, validity of the password using the verification information; granting, by the authentication device, access by the user device to a secure resource when the password is valid; sending no indication of an invalid password to the user device when the authentication device determines the password is invalid; and blocking access of the user device to the secure resource when a predetermined number of passwords are determined to be invalid by the authentication device.
