SMS Absolute Authentication (OTP API)
Overview
SMS Absolute Authentication (OTP API) is a dedicated API for sending One-Time Passwords (OTP) via SMS to perform user verification.
It can be used for scenarios such as account registration, login two-factor authentication, and any process where verifying a user’s identity is required.
As a pioneer in the SMS industry, Xoxzo has supported countless businesses and services over the years.

In addition, the sending cost is one of the lowest in the industry (our survey). Please find the current price in the pricing page.
