SMS verification enables double-checking of a user’s identity on websites, apps, banks, and social networks. Companies will text you a verification code when you submit your login and password. This procedure is known as SMS verification. That code needs to be entered to confirm a login. There are additional names for SMS verification. The terms SMS authentication, SMS-based two-factor authentication (2FA), and SMS one-time password are all possible (OTP). Because it doesn’t require downloading any new apps or services, consumers have grown accustomed to this kind of authentication over time.
