In this article, I’ll briefly discuss 2-factor authentication and it’s importance.
This article provides information to configure the best OTP SMS API service from reliable providers in India?
1. What is One Time Password
An OTP is also known as 2-factor authentication, is a security strategy to improve user security by requiring the user to enter a password, typically delivered via SMS. It could be used to complete an online transaction, make a payment from his/her bank account, or order food or product online.
It is valid only for a single transaction or session.
Essentially, accessing your bank account or online account requires a combination of something you know (Your account password) and something you have (Your OTP in the phone). After all, hackers or thieves might steal your account password, it’s unlikely they’ll be able to steal your phone too.
Besides that, User authentication is most important for any online business, banking or financial sites. There are many OTP SMS providers who offer API to send OTP via SMS, Email or voice call.
Even more, Authenticating user identity with very secured confirmation process which helps the user to secure their transactions with amazing online experiences and thus avoiding frauds and scams.
2. How they can hack you?
Enterprises can power their mission-based messaging system with customer’s preferences. OTP is one such solution which delivers seamless boundary experience to customers as well as business owners.
One Time Passwords are highly useful in online transactions like
- User authentication

3. Advantages of OTP SMS
- Provides a secured platform for critical authentication messages
- Standard cost and simple feature
- Supports globally
- SMS gets delivered for sure
API supports Unicode texts, which means OTP SMS can be sent in any regional languages such as Hindi, Telugu, Tamil, Kannada, Malayalam, Marathi, Bengali, etc.
SMS goes with six alphabetical sender ID, It should be the company/product/service name of the sender.
A standard single English language SMS counts as 160 characters. But if it’s Unicode then it contains 70 characters.
4. Pricing and Quality
There are multiple SMS gateway providers in India who offers API and SMS application for generating OTP SMS. As OTP has to be delivered at any cost, Certainly, the pricing of this token service may be a bit higher compared to standard alert or text marketing services.
If you need the quality in service and super fast technical support, certainly, you must look into standard SMS providers. If you start looking for cheap rate provider’s then you might end up with a loss of money and time.
So, never ever compromise on quality just because you have an option for low rates. Certainly, You can’t run a business if your customer is not getting OTP on time. Think about it.
Due to that reason, Adding 2-Factor authentication is the only thing by which you can keep your customers safe and hassle-free as a business owner.
Now, the question is how to integrate?
Setting up OTP varies from platform to platform such as Java, Dotnet, WordPress, Magento, etc. However, the internal procedure remains the same for any platform. Here it is:
- Getting the mobile number as an input from the customer ( Enter mobile number)
- Generate One Time Password and store it in a session
- Send One Time Password to the mobile number using SMS API
- Get OTP code from the customer and verify with the OTP token that was stored in the session (step 2)
- If the passcode matches – Proceed, if not display Invalid OTP message to the customer.
How the API looks like?
To verify user mobile number you must have SMS API with some credits. For this, you have to get an account from any reliable service providers.
In general, API looks like below one:
https://www.loginurl.com/bulksms/bulksms?username=XXX&password=XXX&type=0&dlr=1&destination=XXX&source=XX&message =Your OTP is XXXX
All the parameters that are mentioned in the API will be provided to you by your provider. However, I’ll walk you through its basic definition:
- Login URL – The URL which will be used to login to your SMS account
- Username – Your SMS account login username
- Password – Password to your account
- Type – Send SMS in English/Hindi/Kannada/Telugu/Tamil/Malayalam or some other language
- dlr – Delivery report needed or not
- Destination – Mobile number
- Source – Sender Identity of 6 alphabets
- message – the OTP message you want to send
If I send the SMS to a single number I will get the below response from the browser:
What does it mean?
- 1701 – Response code; Whether your SMS has been submitted or not
- 9199812XXXXX – Mobile number
- 37308b67-1811-477b-88f2-8b279e0f0813 – Unique ID that generates with every SMS submission
