De användare som fick en massa meddelanden via tvåfaktor-inloggningen har fått meddelanden på grund av en bugg, säger Facebook nu i ett uttalande.

It was not our intention to send non-security-related SMS notifications to these phone numbers, and I am sorry for any inconvenience these messages might have caused. We are working to ensure that people who sign up for two-factor authentication won’t receive non-security-related notifications from us unless they specifically choose to receive them, and the same will be true for those who signed up in the past. We expect to have the fixes in place in the coming days. To reiterate, this was not an intentional decision; this was a bug.

Den gammal funktion ledde också till att de användare som svarade på de meddelanden de fick, publicerades på deras Facebook-konto.
