Why we emailed you a sign-in code

If you sign in with your password, Google or Microsoft from a kind of device or a country your account hasn't used before, we email you a 6-digit code to make sure it's you. Enter it to finish signing in. This doesn't happen if two-factor is on, because the authenticator code already proves it's you.

If you get a code you didn't ask for, someone may know your password. Don't share the code, change your password and turn on two-factor.
