Identification of a related computing device for automatic account login

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving, from a user computing device, a login request to a user account that includes a unique identification (ID) of the user computing device and an internet protocol (IP) address of the user computing device;
• identifying one or more user computing devices that have logged in to the user account using a same IP address as the user computing device based on a user ID of the user account and the unique ID of the user computing device;
• determining if one or more unique IDs corresponding to the one or more user computing devices that have logged in to the user account are correlated with the unique ID of the user computing device;
• and
• sending data corresponding to login information used by the one or more user computing devices to log in to the user account to the user computing device for automatic account login if the one or more unique IDs corresponding to the one or more user computing devices that have logged in to the user account are correlated with the unique ID of the user computing device.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, from a user computing device, a login request to a user account that includes a unique identification (ID) of the user computing device and an internet protocol (IP) address of the user computing device;
• identifying one or more user computing devices that have logged in to the user account using a same IP address as the user computing device based on a user ID of the user account and the unique ID of the user computing device;
• determining if one or more unique IDs corresponding to the one or more user computing devices that have logged in to the user account are correlated with the unique ID of the user computing device;
• and
• sending data corresponding to login information used by the one or more user computing devices to log in to the user account to the user computing device for automatic account login if the one or more unique IDs corresponding to the one or more user computing devices that have logged in to the user account are correlated with the unique ID of the user computing device.
