Tokens and Biometrics
Another way to authenticate users is to use tokens or biometrics. Tokens are something you have, but biometrics are something you are, such as your physical characteristics. A one-time password is an example of a token, as is a bank card with a chip. Fingerprints or iris scans are examples of biometrics. As you watch, pay attention to the description of tokens and biometrics, and the common tokens and biometrics used today. What are some common drawbacks with tokens and biometrics? How do tokens authenticate? Biometrics do not authenticate by comparing photographs of the fingerprints or iris, so how do they authenticate? Which biometric authentication is most secure? Which one is most expensive and which one is the least secure?
