1. A system for generating a real-time audio token for multi-factor audio authentication, the system comprising:
at least one network communication interface;
at least one non-transitory storage device; and
at least one processing device coupled to the at least one non-transitory storage device and the at least one network communication interface, wherein the at least one processing device is configured to:
determine that a user has initiated accessing an entity resource, via a user device of the user;
in response to determining that the user is accessing the entity resource, cause a cryptographic device associated with the user to generate and emit a dynamically varying continuous audio tone, wherein the dynamically varying continuous audio tone is a tone that is inaudible to one or more users and audible to one or more recording devices comprising the user device that is to be recorded with a password that is provided by the user to access the entity resource, wherein causing the cryptographic device to generate and emit the dynamically varying continuous audio tone comprises:
determining strength of the password, via an artificial intelligence engine;
selecting a number of plurality of frequencies for generating the dynamically varying continuous audio tone based on the strength of the password;
causing the cryptographic device to start generating the dynamically varying continuous audio tone with a first frequency of the plurality of frequencies; and
causing the cryptographic device to switch to each of the other frequencies of the plurality of frequencies after a determined time interval;
perform authentication of the user based at least in part on the dynamically varying continuous audio tone;
determine that the authentication based at least in part on the dynamically varying continuous audio tone is successful; and
allow the user to access the entity resource based on determining that the authentication based at least in part on the dynamically varying continuous audio tone is successful.
