Start a conversation about Identity and Access System will always involve one or all of the authentication techniques. Some Identity and Access Systems deployments might integrate in some way at least one.

The authentication techniques are also known as the Three “something” technique and this “something” is: Something you know, Something you are and something you have.

The three “something” categories are the common means of classifying authentication techniques.

– Challenge questions (and their corresponding answers)
o something you are
– Biometrics, such as a fingerprint or voice recognition
o Something you have
– Physical token, such as a bank card, RSA token
