Scalable authentication between heterogeneous services

A computer implemented method for authenticating two or more services for communication, comprising:

• receiving, by one or more processor, a request for a private credential of a first service of the two or more services from the first service, wherein the request includes identity information of the first service;
• generating, by the one or more processor, the private credential of the first service based on the identity information of the first service, wherein the private credential of the first service is encrypted for a secure transfer;
• storing, by the one or more processor, a key for the private credential of the first service in a local database;
• and
• sending, by the one or more processor, the private credential of the first service to the first service such that the first service may securely communicate with another service of the two or more services by use of the private credential of the first service.
