Centralized gateway server for providing access to services

A method for providing access to services across various development platforms, the method comprising:

• establishing a first secure channel connection between a centralized gateway server and a first voice assistant service provider server associated with a first service provider that supports a first development platform, wherein the establishing the first secure channel connection includes using biometric authentication to authenticate users and to ascertain that certain users are authorized to request certain banking operations, the certain banking operations including one or more of open a banking account, open a card account, transfer funds between different banking accounts of the user, transfer funds from a banking account of the user to a third party's account, and receive currency exchange data;
• receiving, at the centralized gateway server via the established first secure channel connection between the central gateway server and the first voice assistant service provider server, a first user request from the first voice assistant service provider server, the first user request indicating a first banking operation to be performed on behalf of a first user, the first user request configured to operate with the first development platform, wherein the first user request is received from the first voice assistant service provider server associated with the first voice assistant service provider that supports the first development platform;
• performing biometric authentication based on the first user request and previously provided biometric input, the biometric authentication performed without transferring biometric data to another device;
• generating, at the centralized gateway server when the previously provided biometric input matches the first user request, a first service request for performing the first banking operation on behalf of the first user in response to receiving the first user request;
• and
• transmitting, when the previously provided biometric input matches the first user request, the first service request to a first server associated with a first service, to cause the first server to perform the first banking operation on behalf of the first user.

A tangible, non-transitory computer readable medium, or media, storing machine-readable instructions that, when executed by one or more processors, cause the one or more processors to:

• establish a first secure channel connection between a centralized gateway server and a first voice assistant service provider server associated with a first service provider that supports a first development platform, wherein the establishing the first secure channel connection includes using biometric authentication to authenticate users and to ascertain that certain users are authorized to request certain banking operations, the certain banking operations including one or more of open a banking account, open a card account, transfer funds between different banking accounts of the user, transfer funds from a banking account of the user to a third party's account, and receive currency exchange data;
• receive, via the established first secure channel connection between the central gateway server and the first voice assistant service provider server, a first user request from the first voice assistant service provider server, the first user request indicating a first banking operation to be performed on behalf of a first user, the first user request configured to operate with the first development platform, wherein the first user request is received from the first voice assistant service provider server associated with the first voice assistant service provider that supports the first development platform;
• perform biometric authentication based on the first user request and previously provided biometric input, the biometric authentication performed without transferring biometric data to another device;
• generate, when the previously provided biometric input matches the first user request, a first service request for performing the first banking operation on behalf of the first user in response to receiving the first user request;
• and
