📚 Topic Summary
Two-Factor Authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity. This adds an extra layer of protection beyond just a password, making it significantly harder for unauthorized individuals to access your accounts. Common 2FA methods include something you know (like a password), something you have (like a phone receiving a code), or something you are (like a fingerprint).
Think of it like this: your password is the key to your front door, but 2FA is like having a security guard who also needs to see your ID before letting you in. Even if someone steals your key (password), they still need that ID (the second factor) to get in.
