Biometrics and Multi-Factor Authentication Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What does authentication mean?

Checking you are who you say you are.

Using unique body features to prove your identity.

Fingerprint and face recognition.

You cannot forget them, and they are quick to use.

A wet or dirty finger or poor lighting can stop a match.

Tricking a sensor with a fake finger, face, or voice.

You cannot change your fingerprints or face like a password.

Multi-Factor Authentication: using two or more different factors to log in.

Something you know (password), have (phone or token), and are (biometric).

2FA is a type of MFA that uses exactly two factors.

If a password is stolen, the attacker still needs the second factor.

Enter a password, then a 6-digit code from an app or text.
