Elevate Business Security and Trust with SMS Verification

by | Feb 23, 2024

SMS verification

Passwords have long been the go-to method for safeguarding digital assets worldwide. However, with cyber threats becoming more sophisticated, passwords alone may not be enough to protect your data. An alarming 80% of confirmed data breaches are linked to weak or stolen passwords. SMS verification can effectively mitigate the risks of compromised passwords. Discover more about SMS verification and how it bolsters your digital security. 

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.

Advantages of Using SMS Verification Codes

Here are the top benefits of SMS verification. 

More Secure 

Sending OTP codes via SMS to the user’s device is a simple way to implement two-factor authentication (2FA). SMS verification makes it more challenging for threat actors to access sensitive information by introducing an extra authentication factor besides passwords. 

Seamless User Experience

Unlike other forms of authentication, such as CAPTCHA or biometric scans, SMS verification is familiar to users, resulting in a seamless user experience.

Cost-Effective

SMS verification is an affordable solution in most markets for businesses of all sizes, compared to more complex authentication methods.

Convenient

There are more than 5.4 billion people mobile users worldwide. Users can receive SMS verification codes on devices that they always have with them, eliminating the need for additional software or hardware. 

SMS authentication does come with certain drawbacks. It is susceptible to frauds such as SIM swapping and Artificially Inflated Traffic (AIT). Enterprises should remain vigilant about such cyber threats to avoid loss of revenue or reputation. Moreover, people losing phones and synced devices receiving OTPs can potentially result in access by unauthorized users.

    • How SMS is Used for Verification Across Industries

      SMS verification is a versatile and widely adopted security measure that enhances authentication processes, protects sensitive information, and mitigates the risks of fraud across various industries.

      Banking and Finance

      Banks and financial institutions commonly employ SMS to verify customer identities during account registration, verifying login attempts and actions such as fund transfers or account changes. This helps prevent identity theft and fraudulent transactions.

    • E-commerce

      SMS is often used for authentication during account sign-up, login, and checkout processes in e-commerce websites or apps. This helps prevent account takeovers, unauthorized purchases, and fraudulent refunds, thereby safeguarding both the e-commerce platform and its customers.

      Healthcare

      Healthcare organizations use SMS verification to secure patient portals, electronic health records (EHRs), and telemedicine platforms. By requiring patients and healthcare providers to verify their identities via SMS OTP codes, healthcare providers can ensure the confidentiality of sensitive patient information while complying with regulatory requirements like the Health Insurance Portability and Accountability Act (HIPAA).

      Travel and Hospitality

      Airlines, hotels, and travel agencies use SMS codes to authenticate customers during booking processes, account logins, and accessing reservation details. This helps prevent unauthorized access to travel itineraries, loyalty accounts, and sensitive personal information.

      Government and Public Services

      Government agencies and public service providers use SMS authentication to confirm identities during tax filings, permit applications, and accessing government portals. 

    • Why is SMS Authentication Important for Business?

       

      Mitigation of Fraud

      SMS verification signifies a proactive approach to fraud prevention, helping protect the business and its customers from financial losses and reputational damage. It deters cyber threats like bot attacks, ensuring only legitimate users can access sensitive information and perform critical actions.

      Regulatory Compliance

      Implementing SMS verification aligns with regulatory frameworks such as the General Data Protection Regulation (GDPR) or the Payment Card Industry Data Security Standard (PCI DSS). Businesses can showcase their commitment to safeguarding customer information and maintaining data privacy by adhering to these regulations.

      Fostering Trust 

      In addition to strengthening security, SMS authentication plays a critical role in cultivating customer trust. Businesses can reassure users that their data is secure, enhancing confidence in the brand.

      Reliability and Uptime

      Ensure that the SMS verification service has a reliable infrastructure and high uptime to prevent authentication delays or service interruptions. OTP delays can disrupt the user flow, causing in potentially leading to the abandonment of the authentication process. Additionally, prolonged delays can erode trust in the business. Check for redundancy and failover mechanisms to ensure continuity of service. 

      Scalability

      Choose a service provider that can keep up with your growing business needs. Whether you’re a small startup or a large enterprise, the SMS verification service should be able to handle increasing volumes of authentication requests without compromising performance or security.

      Developer-Friendly APIs

      Look for an SMS verification service that provides easy-to-use APIs and SDKs for seamless integration into your existing applications and systems. 

      Customization Options

      Pick a service provider that allows you to tailor the sequence of OTP generation according to your preferences. 

      Analytics and Reporting

      Consider an SMS verification service that provides tools to track authentication metrics, monitor usage patterns, and detect suspicious activities.

      Evaluate the quality of support offered by the SMS verification service provider. Look for service level agreements (SLAs) that guarantee response times, uptime guarantees, and resolution of issues to ensure prompt assistance for urgent issues.
