SMS verification involves the sending of an OTP to the user's mobile phone through SMS. The password is then used to log in to an app or website that requires verification. SMS two-factor authentication can be used to confirm the identity of the user who is trying to sign up for a brand new account, sign in to an existing account, or make a purchase.
