What Is SMS Authentication?

SMS authentication is a type of two-factor authentication (2FA) that enhances security by utilizing a user's phone number for identity verification. A unique 4–6 digit OTP SMS code is sent to the user's registered phone number.

Acting as a reliable means of verifying a user's ownership, this process helps businesses strengthen identity authentication while keeping it convenient and user-friendly. 2FA can also be completed using flash call authentication instead of SMS.
