Esendex helps businesses communicate quickly, simply, and cost-effectively with our OTP (one-time passcode) verification services through SMS to level up your business’s security.
What is OTP Verification via SMS?
OTP verification through SMS secures online accounts or transactions by requiring users to enter a unique code sent to their mobile phone via SMS. This authentication method is useful in many industries, from online banking to e-commerce, where secure authentication is essential.
When an OTP is sent through SMS and verified, it provides an additional layer of security by confirming that the person attempting to access the account or complete the transaction is the legitimate account holder.
OTP Verification via SMS: How Does It Work
OTP verification via SMS is a straightforward process. When users attempt to access an account or complete a transaction, they are prompted to enter their mobile phone number. Next, an OTP code is generated and sent to the mobile phone via SMS.
To complete the verification process, the user must enter that one-time passcode on the website or app. This is usually a time-sensitive task with a code that expires within 5 to 10 minutes of being sent to the user for security.
Advanced Features of OTP Verification via SMS with Esendex
At Esendex, we provide advanced features to enhance the security of your OTP verification service through SMS, including:
Customized Sender IDs
Our customized sender ID feature will allow you to personalize SMS messages with your company name. Instead of getting a generic message and code, your customers will be reminded of your branding each time they interact with your app or website. This will create a more professional and trustworthy image for your business when your customers receive your communication.
Delivery Receipts
With our delivery receipt feature, you will be notified each time your SMS message has successfully reached your customer’s inbox. This will clear up any speculation by clearly confirming your message’s destination.
Time-based One-Time Passwords (TOTP)
Time-based one-time passwords present an additional layer of security by expiring after a set period. When your customers attempt to sign in or complete the transaction, they will only have a short time to use the one-time password sent to their phone.
If they don’t make it in time, they must request a new OTP to complete their action. This will prevent cyber criminals from accessing the code later and authenticating themselves as customer fraudulently.
Benefits of SMS OTP Verification
SMS OTP Verification has several benefits that can help your business grow:
Safety
SMS OTP verification is a secure method of protecting data, accounts, and transactions. Since they can only be used once and are time-bound, it becomes more difficult for accounts to be hacked or fraudulent transactions to be completed. Your systems and customer accounts will remain secure, as expired codes prevent unauthorized access at a later time.
Reliability
SMS OTP verification is the most reliable method of authentication. It’s one of the only ways to ensure the user can access a system or account, reducing the risk of fraud and unauthorized access to critical information. SMS verification via OTP has been a trusted strategy for securing digital transactions for years.
Easy Implementation
An SMS OTP verification system is easy to implement, even without technical skills or a specialized department. It typically only requires finding a suitable provider and following simple steps to integrate their API on the back end of your website or app. Once you have activated the service, your customers will be ready to receive authentication codes.
Reduces Password Fatigue
SMS OTP verification helps to reduce password fatigue by eliminating the need for users to remember complex passwords or security questions. Since OTPs are sent directly to the user’s phone, they won’t need to remember it for long. Instead of using weak passwords or reusing the same ones, they can simply copy and paste a code for each account.
Improves Customer Experience
SMS OTP verification makes it easier for customers to access their accounts and complete secure transactions, improving the overall customer experience. Your customers are much more likely to be satisfied with this system in place and trust your brand for account security.
