How does the second step at sign-in work?

The second step is a 6 digit code from an authenticator app, such as Google Authenticator, asked for after your password. It keeps your account safe even if someone learns your password. You turn it on in Settings, Security.

Turning it on logs you out on every other device. After 5 wrong codes in a row, you must wait 15 minutes and sign in again with your password.
