User authentication based on biometric handwriting aspects of a handwritten code

A technique authenticates a user. The technique involves receiving, by processing circuitry, a handwritten code. The technique further involves performing, by the processing circuitry, a set of assessment operations which includes (i) a handwriting evaluation to analyze a set of biometric handwriting aspects of the handwritten code and (ii) a code evaluation to analyze code accuracy of the handwritten code. The technique further involves providing, by the processing circuitry, an authentication result based on the set of assessment operations. Such a technique strengthens security by including a "who you are" factor (i.e., handwriting biometrics uniquely identify the genuine user).
