Patent attributes
A system for granting access to an account at an access device includes a computer server having a hardware processor and a memory storing a software code. The hardware processor executes the software code to receive a login request from the access device through a first communications socket, open a second communications socket between the access device and the computer server, transmit a verification request message including a required call-to-action to a verification device through a third communications socket, and receive a verification response message verifying that the required call-to-action has been completed at the verification device. Upon receiving the verification response message, the software code sends an access token for accessing the account to the access device through the second communications socket, receives the access token from the access device, and grants the access device access to the account.
