What is SMS OTP?
The OTP ( SMS ) “One-Time Password” SMS is a message containing a unique 6-digit code that allows you to you to authenticate online via SMS. The code, which comes from another device (mobile), serves as a second factor.

Best known for verifying online payments, this SMS also helps protect sensitive customer data, secure connections to applications, validate electronic signatures, and even verify a user’s identity during registration. It adds a second factor of authentication: verifying a person’s identity based on what they have (their phone).
The OTP ( SMS ) is the essential component of 2FA (two-factor authentication), also known as “two-factor identification” or “multi-factor authentication” (MFA). The code contained in the message adds a layer of security to customers’ online activities and helps address the shortcomings of static passwords.
