What is SMS Verification?

How Does SMS Verification Work?

The SMS verification process is straight and efficient. Here is a step-by-step breakdown of how it works:

  • User Request: A user initiates an action that requires verification, such as signing up, logging, or password reset for a new account.
  • Code Generation: The system generates a unique, time-sensitive SMS verification code. This code is usually a number of 4-6 digits.
  • Code delivery: The code is sent to the user's mobile device via SMS message. It is often known as an online SMS message.
  • Code Entry: The user receives the SMS and enters the code into the required field on the website or app.
  • Verification: The system checks the code. If it matches, the user gains access. If not, they may request a new code.

This process ensures that only the person with access to the registered mobile device can complete the action, adding an extra layer of security.
