dual factor

process where the session is authenticated on both ends (prevents man in the middle attacks)
mutual auth
biometrics - stipulates that we should be able to find the chosen characteristic in the majority of people we expect to enroll in the system
universality
biometrics - measure of how unique a characteristic is
uniqueness
biometrics - test how well a characteristic resists change over time/age
permanence
biometrics - measures how easy it is to acquire a characteristic with which we can later use to authenticate
collectability
biometrics - set of metrics that judge how well a given system functions
performance
biometrics - measure of how acceptable the characteristic is to the users
acceptability
biometrics - describes how easily a system can be tricked by a falsified biometric identifier
circumvention
physical devices that generate an OTP
hardware tokens (something you have)
applications that generate an OTP
software tokens
