Methods and systems to authenticate a user account using an internet protocol (IP) address

A method for authorizing access to a user account by a carrier hotspot device attached to a carrier network, wherein the method comprises:

• receiving, by an authentication application of an identity and access management system, from a carrier hotspot device connected to the carrier network, a request to create or log in to the user account, wherein the request includes an Internet Protocol address of the carrier hotspot device, wherein the Internet Protocol address is assigned to the carrier hotspot device when the carrier hotspot device attaches to the carrier network;
• extracting, by the authentication application, the Internet Protocol address of the carrier hotspot device from the request;
• transmitting, by the authentication application to an identification application in a core network of the carrier network, the Internet Protocol address of the carrier hotspot device, requesting the identification application to provide an identifier of a device registered with the carrier network that has been allocated the Internet Protocol address;
• receiving, by the authentication application from the identification application, the identifier of the carrier hotspot device associated with the Internet Protocol address;
• and
• providing, by the authentication application to the carrier hotspot device, an indication that the carrier hotspot is permitted to create the user account or granted access to the user account.

A system comprising:

• at least one processor;
• at least one non-transitory memory;
• an authentication application, stored in the at least one non-transitory memory, which when executed by the at least one processor, causes the at least one processor to be configured to:
• obtain an Internet Protocol address of a carrier hotspot device, wherein an access device is connected to a carrier network using the carrier hotspot device, wherein the Internet Protocol address is assigned to the carrier hotspot device when the carrier hotspot device attaches to the carrier network;
• an identification application in a core network of the carrier network, stored in the at least one non-transitory memory, which when executed by the at least one processor, causes the at least one processor to be configured to:
• receive, from the authentication application, the Internet Protocol address of the carrier hotspot device;
• determine an identifier of the carrier hotspot device associated with Internet Protocol address based on address-to-identifier mappings accessible to the identification application;
• and
• transmit the identifier to the authentication application, and
• wherein the authentication application further causes the at least one processor to be configured to provide, to the access device, an indication that the access device is permitted to create a user account or granted access to the user account.
