Authentication#

You'll be authenticating with a a lot of systems during your day to day. Authentication essentially comes down to who you are. There are a tonne of different ways to authenticate to a system. We'll cover some of those here.

There are things we call "factors" that go into the authentication process:

1. Knowledge: something the user knows
2. Ownership: something the user has
3. Inherence: something the user is

Combined we get authentication.
