I see 2FA is often misunderstood by people. The basic premise with 2FA is that you combine “something you know” with “something you have”.

You are already part of the 2FA — you’re the first factor: “something you know”.

The second factor: “something you have” — often a personal device, or an object. This is ideally something no one else can be in possession of at the same time as you are.
