To enable two-factor authentication, tap the first item in the Control Center menu, labeled Two-Factor Authentication; click on the button at the bottom of the screen labeled Turn On Two-Factor; confirm your Ring account password in the appropriate field and tap the Continue button. Then specify the smartphone number to which Ring must send a verification code and tap the Continue button.
Ring sends a six-digit code to your phone. Type this in the appropriate field, tap Continue, and then tap it again on the next screen. That is all, you have enabled two-factor authentication. Every time you log in to the Ring app from a new device, you need both your password and a one-time six-digit code that Ring sends to your phone via text message. This must ensure that ensures that even if the account is compromised, no one can access your account unless they have your account details and also have in possession of your phone and it
That said, the type of two-factor authentication that Ring uses is not impenetrable for hackers, mainly because SMS is not a secure means of communication. Non-encrypted text messages can be intercepted and hackers can steal your phone number and reassign it to another SIM card.
