What is multi-factor authentication for cloud accounts?

Multi-factor authentication, or MFA, is a second lock on your account. Even if someone steals your password, they can't get in because they don't have the second thing your account asks for. A code from your phone. It's like having both a key and a fingerprint to unlock a door.

Multi-factor authentication adds a second security check when you log in to your cloud account. The first factor is your password. The second factor is something only you have. Like a code on your phone, a fingerprint, or an app. When you type your password, the account sends a code to your phone, and you have to type that code to get in.
