Systems and methods for secure online credential authentication

A system for secure online credential authentication, the system including:

• a data storage device that stores instructions system for secure online credential authentication;
• and
• one or more processors configured to execute the instructions to perform a method including:
• receiving, at a server, hashed first identification information as a hash from a first identity provider;
• accessing, by the server from a database, previously stored hashed identification information stored as a hash in association with a previous identity provider, wherein the previously stored hashed identification information was received by the server as a hash;
• comparing, by the server, the hashed first identification information as a hash to the previously stored hashed identification information as a hash, wherein the hashed first identification information was hashed prior to being received by the server, and the previously stored hashed identification information was hashed prior to being received by the server;
• comparing, by the server, the first identity provider to the previous identity provider;
• and
• transmitting, by the server, an authentication result based on the comparing the identification information and the comparing the first identity provider to the previous identity provider.

A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to perform a method for secure online credential authentication, the method including:

• receiving, at a server, hashed first identification information as a hash from a first identity provider;
• accessing, by the server from a database, previously stored hashed identification information stored as a hash in association with a previous identity provider, wherein the previously stored hashed identification information was received by the server as a hash;
• comparing, by the server, the hashed first identification information as a hash to the previously stored hashed identification information as a hash, wherein the hashed first identification information was hashed prior to being received by the server, and the previously stored hashed identification information was hashed prior to being received by the server;
• comparing, by the server, the first identity provider to the previous identity provider;
• and
• transmitting, by the server, an authentication result based on the comparing the identification information and the comparing the first identity provider to the previous identity provider.
