What is OTP SMS and How Does It Work Step by Step?

OTP (One-Time Password), is a short-term, one-time 'digital key' used to verify the digital identity of your users. As one of the most common and reliable methods of Two-Factor Authentication (2FA), it provides a critical security layer against cyberattacks and unauthorized access on online platforms.

Its main purpose is to confirm that the person performing a transaction is indeed that person, by verifying through the registered mobile phone number. This simple yet powerful method has become a standard security procedure, especially in sensitive processes such as user login, password reset, online payments, and money transfers.

How the OTP System Works in 4 Steps:

User Action: The user initiates a secure transaction on your website or mobile app (e.g., clicking the 'Login' or 'Confirm Payment' button).
Automatic Code Generation: This action triggers your system in the background. Through the Figensoft API, your system instantly generates a unique and random verification code (usually 4-6 digits).
Instant SMS Delivery: The generated one-time password is sent within seconds to the user’s registered mobile phone as a high-priority SMS.
Verification and Access: The user enters the received code into the appropriate field on the screen. The system verifies the code’s accuracy and allows the user to securely complete the transaction.

OTP SMS vs. Standard Bulk SMS: Key Differences
