US Patent 11386194 Generating and validating activation codes without data persistence

The current embodiments offer a method to generate, send, and authenticate users through validations codes without the need for data retention. Codes are generated each time they are sent and received based on original and identifiable inputs. They are then compared to authenticate a user. Eliminating the need for data retention or persistence removes the risks associated with keeping data on the service provider's storage as can be maliciously accessed.
