Secure serverless multi-factor authentication

A computing device comprising:

• memory;
• and
• one or more processors configured to:
• receive indications of values of authentication factors associated with an entity;
• hash the values of the authentication factors to generate double hashed values of the authentication factors;
• compare the double hashed values of the authentication factors with trusted authentication information that is encoded in entity credentials associated with the entity;
• and
• determine, based at least in part on comparing the double hashed values of the authentication factors with the trusted authentication information, whether the entity is a trusted entity.

A non-transitory computer readable storage medium storing instructions that, when executed by one or more processors of a computing device, cause one or more processors of a computing device to:

• receive indications of values of authentication factors associated with an entity;
• hash the values of the authentication factors to generate double hashed values of the authentication factors;
• compare the double hashed values of the authentication factors with trusted authentication information that is encoded in entity credentials associated with the entity;
• and
• determine, based at least in part on comparing the double hashed values of the authentication factors with the trusted authentication information, whether the entity is a trusted entity.
