<p>A method for authenticating a person with respect to a host. The host requests a temporary password from the person for accessing a service of the host. Random-based information is generated and provided to the person via a communication device as an input value for an algorithm from which the temporary password is calculated. The same algorithm is used by the person and by the host in order to calculate the password, and after a match is determined between the password calculated by the person and by the host, the person is granted access to the service of the host. The random-based information is displayed to the person as part of a password request routine of the host, and the person responds by inputting a temporary password. The random-based information is used solely as an input variable for the secret algorithm which ascertains the temporary password.</p> |
