Explanation
Authentication factors fall into three categories: something you know, something you have, and something you are. In this scheme, both the password and the PIN are 'something you know' - they count as one factor type despite being two separate credentials. The smartphone-generated dynamic token is 'something you have' - a second, distinct factor type. Because only two different factor categories are used (knowledge + possession), this is two-factor authentication (2FA), not multi-factor (which would require three distinct factor types). Biometric security involves physical traits (fingerprints, retina), which are absent here. Single-factor authentication uses only one category.
