OTP Mail (One-Time Password Delivery via Email)

What Is OTP Mail and How Does It Work?

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

Its main purpose is to confirm that the person performing a transaction is indeed the rightful user, by verifying through the registered email address. This simple yet powerful method has become a standard security procedure, especially in sensitive operations such as user logins, password resets, online payments, and membership confirmations.

How the OTP Mail System Works in 4 Steps:

• 1 User Action
  • Your user initiates a secure action on your website or mobile app (for example, clicking ‘Login’ or ‘Forgot Password’).
• 2 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).
• 3 Instant Email Delivery
  • The generated one-time password is sent within seconds to the user’s registered email address via a secure infrastructure.
• 4 Verification and Access
  • The user enters the received code into the designated field on the screen. The system verifies the code’s validity and allows the user to securely complete the transaction.
