Two Factor Authentication SMS (2FA) or SMS authentication service is a way to add an additional security layer to your account. SMS Two Factor Authentication (Double Factor Authentication) is a security verification process triggered before a user logs into an eCommerce platform, software, or mobile application.
In the log-in process, the user is automatically sent an SMS to their mobile number and email containing a unique numeric OTP code. This OTP code is inputted by the end-user, validating themselves as the legitimate owner logging into the online account.
We have designed our own infrastructure for two-factor authentication. This system is heavily tested, hardened, and highly secure.
The first factor is your usual password standard for any account. The second factor is a verification code retrieved via SMS or an email token.
2FA is conceptually similar to a security token device that banks require for online banking. Other standard industry names include OTP (one-time password) and TOTP (Time-based One-time Password algorithm).
