Abstract: Example embodiments provide two-way authentication. A computing device accesses a server of a site. In response to the accessing, a list of token values including a first token value generated by an authentication server is received. The computing device displays the list of token values, whereby the list of token values is compared to a first token value associated with the computing device to determine whether the first token value associated with the computing device is in the list. A match in the first token value associated with the computing device to the first token value in the list provides authentication of the server of the site at the computing device. A second token value associated with the computing device is received in response to the match. The second token value associated with the computing device is transmitted and used to authenticate a user at the server of the site.

The computing device displays the list of token values, whereby the list of token values is compared to a first token value associated with the computing device to determine whether the first token value associated with the computing device is in the list. A match in the first token value associated with the computing device to the first token value in the list provides authentication of the server of the site at the computing device.

The second token value associated with the computing device is transmitted and used to authenticate a user at the server of the site.

Abstract: Example embodiments provide a method that includes generating, at an authentication server, a first token value. The authentication server receives a request for the first token value from a server of the site being accessed by a device of a user. The first token value is transmitted to the server of the site, causing the server of the site to transmit a list of token values including the first token value to the device. The list is presented on the device, and used to compare to a first token value generated by a password device to determine whether the first token value of the password device is presented in the list. The authentication server receives a second token value from the server of the site, whereby the second token value is used to authenticate the user accessing the site, and verifies the second token value to authenticate the user.

The authentication server receives a second token value from the server of the site, whereby the second token value is used to authenticate the user accessing the site, and verifies the second token value to authenticate the user.

Abstract: A system is illustrated as including a One-Time Password (OTP) device operatively coupled to a computer system to receive data, and a server operatively coupled to the computer system via a network connection. A method is illustrated as including receiving and verifying credentials of a user accessing the site. In response to verifying the user, a request is transmitted to an authentication server for a first token value corresponding to the user. The first token value is received from the authentication server. The first token value is displayed to the user. The first token value is displayed at the same time as part of a list with other token values to the user. The user compares the list of token values to a token value generated by a password device to determine whether the token value generated by the password device is included in the list of token values.

Abstract: A method includes generating first and second One Time Password (OTP) token values from a shared clock, receiving a version of the second OTP token value, and comparing the second OTP token value and the version of the second OTP token value. A system includes a generator residing on an authentication server to generate first and second One Time Password (OTP) token values from a shared clock, a transmitter residing on the authentication server to transmit the first OTP token value, a receiver residing on the authentication server to receive a version of the second OTP token value, and a comparator to compare the second OTP token value and the version of the second OTP token value to authenticate a site and a user.

Abstract: A system and method are illustrated as including receiving a request for a current time and transmitting the current time to a password device. The current time is used to synchronize a clock in the password device to reflect the current time of an authentication server. The synchronized clock is used to generate a first token value at the password device. A request for the first token value is received from a server of the site by the authentication server. The server of the site is provided with the first token value. The server of the site sends a list of token values including the first token value to a computing device associated with the password device. The list of token values, presented at the same time on the computing device, are compared to the first token value generated by the password device to determine a matching first token value.
