System and method for secure nework login

A computer implemented method executing on a client device and a personal user device for authenticating a user to a server computer comprising:

• sending an access request to the server using the first client device and a network that is operatively connecting the server and the first client device;
• receiving a unique login identifier from the server at the client device as a displayed machine readable code via the network;
• scanning the displayed machine readable code using the personal user device to obtain the unique login identifier;
• sending a cryptographically secured message from the personal user device that includes a personal user device identifier and the unique login identifier, wherein the unique login identifier is further cryptographically secured;
• and then,
• interacting with the server on the client device to access a user account on the server that is logged-in as a result of sending the message.

A server system for authenticating a user using a client device to the server comprising:

• memory storing processor-executable instructions;
• and
• a processor in communication with the memory and operative in conjunction with the memory to execute the stored instructions to:
• receive an access request from the client device using a network;
• send a unique login identifier to the client device;
• receive a message originating from the user including a personal user device identifier and the unique login identifier;
• determine an identity of the user using the personal user device identifier;
• determine a server access request response associated with the user and the client device using the unique login identifier;
• and
• log in the user to the server on the client device.

A computer implemented method executing on a server computer for authenticating a user using a client device to the server computer comprising:

• receiving an access request from the client device using a network;
• receiving secret authentication factor data from the user;
• using the secret authentication data to obtain a public key for the user;
• encrypting an account access session ID using the public key;
• encoding the account access session ID in a two dimensional barcode;
• and
• sending the account access session key to the client device.
