When used alone, any authentication technique provides some security for systems. However, they each have their own drawbacks. The solution to this problem is to combine authentication techniques from multiple factors, such as combining something you know with something you have. This approach is known as multifactor authentication.
- [Instructor] In the last video you learned how…computer systems offer many different authentication…techniques that allow users to prove their identity.…These include something you know, such as a password,…something you are, such as a fingerprint,…and something you have, such as a smartphone.…When used alone, any one of these techniques…provide some security for systems.…However, they each have their own drawbacks.…For example, an attacker might steal a user's password…through a phishing attack.…Once they have the password,…they can then use it to assume the user's identity.…
Other authentication factors aren't foolproof either.…If you use smart card authentication…to implement something you have,…the user may lose the smart card.…Someone coming across it may then impersonate the user.…The solution to this problem is to combine…authentication techniques from multiple factors…such as combining something you know…with something you have.…This approach is known as multifactor authentication.…Take the two techniques that we just discussed,…
