Method and Device for Information System Access Authentication

A method that improves authentication of a client device that logins into a computer system, the method comprising:

• receiving, at a gateway server, a request to login the client device to the computer system;
• establishing, by the gateway server and in response to the request from the client device, a session that corresponds to a session identifier (ID) such that the session ID is retrieved by the client device to create a computer-readable authentication code that includes the session ID and a Uniform Resource Locator (URL) that is provided by the client device for login into the computer system;
• and
• receiving, by the gateway server and from the mobile device, a user name and a password that are retrieved from a list of URLs, user names and passwords in the mobile device and are associated with the URL such that the user name and the password are fetched by the client device to login into the computer system.

An authentication system that improves how users authenticate to a computer system, comprising:

• a client device with a display that displays an authentication code;
• a gateway server that includes a memory that stores session identifiers (IDs) corresponding to sessions that are established in response to requests from the client device;
• and
• a mobile device that communicates with the gateway server over a network and includes:
• a processor;
• a memory that stores a list of Uniform Resource Locators (URLs), user names and passwords;
• and
• an authentication reader that reads the authentication code from the display of the client device to obtain a session ID and a URL that are embedded in the authentication code, wherein the session ID corresponds to a session that is established by the gateway server,
• wherein the mobile device searches in the memory of the mobile device to determine whether a user name and a password that are associated with the URL exist.
