What is it?
Let's start with the definition of authentication. Essentially the process of authentication involves proving you are who you say you are. There are three ways of authenticating:
- Something you have: this is something like an ID or item that you have to prove that you are yourself
- Something you are: this is something physically about you (like a fingerprint) that proves you are yourself
- Something you know: this is something like a password that you know that nobody else would
Where you can use it?
