Systems and methods for fast and simultaneous multi-factor authentication using vector computing

A method of multi-factor authentication (MFA), the method comprising:

• receiving, by a computing device comprising one or more processors, from an authenticated entity, a plurality of authenticated inputs;
• generating, by the computing device a plurality of normalized authenticated inputs;
• generating, by the computing device, an n-dimensional authenticated signature vector corresponding to the plurality of normalized authenticated inputs;
• receiving, by the computing device, a plurality of MFA inputs;
• generating, by the computing device, a plurality of normalized MFA inputs;
• generating, by the computing device, an n-dimensional MFA vector corresponding to the plurality of normalized MFA inputs;
• determining, by the computing device, whether a distance between the n-dimensional authenticated signature vector and the n-dimensional MFA vector is less than an authentication distance threshold;
• and
• based on the distance between the n-dimensional authenticated signature vector and the n-dimensional MFA vector not exceeding the authentication distance threshold, generating, by the computing device, an indication that the plurality of MFA inputs have been authenticated.

One or more non-transitory computer-readable comprising instructions for multi-factor authentication (MFA) that, when executed by a computing platform comprising at least one processor, a communication interface, and memory, cause the computing platform to:

• receive, from an authenticated entity, a plurality of authenticated inputs;
• generate a plurality of normalized authenticated inputs;
• generate an n-dimensional authenticated signature vector corresponding to the plurality of normalized authenticated inputs;
• receive a plurality of MFA inputs;
• generate a plurality of normalized MFA inputs;
• generate an n-dimensional MFA vector corresponding to the normalized MFA inputs;
• determine whether a distance between the n-dimensional authenticated signature vector and the n-dimensional MFA vector is less than an authentication distance threshold;
• and
• based on the distance between the n-dimensional authenticated signature vector and the n-dimensional MFA vector not exceeding the authentication distance threshold, generate an indication that the plurality of MFA inputs have been authenticated.
