how does two factor authentication work?
2FA is like having two locks on a door. The first lock is a regular lock that you open with a key. The second lock is a special lock that requires a secret code to open.

When you want to open the door with 2FA, you first use the key to unlock the regular lock. But then, instead of being able to go through the door right away, you have to enter the secret code into the special lock. The code might be a number that you remember or a code that you get from an app on your phone.

The idea behind 2FA is to make it harder for someone to get into a place or access information, even if they have the key or password. By requiring a second factor (like the secret code), it adds an extra layer of security to protect against unauthorized access.
