What is SMS Verification?

SMS verification, or SMS authentication, is a security measure that uses SMS messages to verify a user’s identity. It adds an extra layer of security to online transactions, account logins, and other digital interactions on websites and apps.  

Traditional password-based authentication has proven to be ineffective against modern cyber attacks, with studies revealing that 96% of the most common passwords can be hacked in less than one second. Even when people adhere to best practices, passwords can be stolen through social engineering. This is why businesses widely implement two-factor authentication (2FA), which makes it more difficult for unauthorized users to gain access, even if they have obtained the user’s password. SMS-based 2FA takes advantage of text messaging to deliver authentication codes to users’ mobile phones, enhancing account security. 

How does SMS Verification Work?

SMS verification requires users to confirm their identity through a unique, temporary code sent to their mobile device via SMS. By introducing this additional step, SMS verification codes significantly reduce the likelihood of unauthorized access and strengthen protection against cyber-attacks. 

Here are the steps involved – 

1. The user is prompted to input their phone number during the account sign-up or registration process on the business website or app.

    

2. The phone number is sent a code the user must enter into the designated field.

    

3. For subsequent login or transaction attempts, once they enter a username and password, the user will receive a unique code or

   one-time password (OTP)

   via SMS on the designated phone number.

    

4. The user inputs the code and gains access to their account or completes the transaction.

Understanding How SMS Verification Works

Using SMS to verify and authorize users is one way to fortify account security. With this process, you can ensure only legitimate users gain access to your business platform. No more worrying about fake accounts or unauthorized access. Let’s explore how SMS verification works and how it can help your business.

What is an SMS Verification?

SMS verification is a safety protocol that confirms the identity of someone trying to use a service or complete a transaction. Online SMS verification sends a text message with a unique code, usually a number, to the user’s mobile number.  

The user must input this code into the service’s verification section to confirm their legitate access as user and finish the SMS verification process. It is impossible to get an SMS verification code without a phone number. 

Common Use Cases for SMS Verification

Companies use SMS to verify customer accounts to bolster security, refine user experience, and safeguard transaction authenticity. Here are some common use cases for SMS verification: 

• Account setup and registration: Use SMS to confirm the user’s legitimate access and validate phone numbers to reduce fake accounts and spam registrations. 
• Two-Factor Authentication (2FA): Add an extra security layer to the login process beyond a username and password to protect user accounts from unauthorized access. 
• Password resets and account recovery: Send an SMS to verify user’s legitimate access or password reset and account recovery to prevent unauthorized access. 
• Authorize transactions: Confirm high-risk transactions or account changes securely. 
• Delivery and order confirmations: E-commerce platforms and delivery services use notifications to confirm orders and delivery schedules and update customers.
