Ring announced today the roll-out of mandatory two-factor authentication (2FA) to all user accounts. Ring also announced that users will have more control of the info they share with third-party service providers. Ring users that won’t have 2FA will be alerted when someone logs into their accounts via the login notifications feature added last December. Google also forcibly enabled 2FA for all Nest accounts a week ago to block automated credential stuffing and dictionary attacks targeting Nest users. The change comes after a series of hacks targeting Ring cameras were reported in December.
