Not always. Authentication is based upon one or more of the following:
A Personal Identification Number (PIN) portrays authentication based upon something known.
No. A fingerprint is a biometric reading which portrays authentication based upon something the user is. Fingerprints, retina scans and DNA samples are all examples of biometric readings.
Yes. Any biometric reading, such as a fingerprint, retina scan or DNA sample portrays authentication based upon something the user is.
Yes.
You cannot portray identification upon something unknown. It must be something known only to the user, or be something the user is (such as a fingerprint, retina scan or DNA sample) or something the user has (such as an ID card).

Not always. Authentication is based upon one or more of the following:Something the user knows (such as a PIN).Something the user has (such as an ID card).Something the user is (such as a fingerprint).
Authentication is based upon either:Something you know (such as a PIN).Something you have (such as an ID card).Something you are (such as a fingerprint, retina scan or DNA sample).Preferably, authentication will combine two or more of the three.
1. Fingerprint.
Three factor authentication is based upon three aspects: something you have, something you know and something you are. For instance, you might be asked to present an ID card (something you have), enter a PIN (something you know) and provide a fingerprint (something you are). The latter is a biometric and may include a retina scan or a DNA sample.
RADIUS requires port-based authentication.
Yes, RADIUS requires port-based authentication.
The most common form of authentication is the password based authentication
