One-Time Passwords (OTPs) are crucial for securing user accounts during the password recovery process.

In this guide, we will show you how to send OTPs using PHP and WASenderAPI, a reliable WhatsApp API for sending secure messages. By integrating WhatsApp OTP for password recovery, you can ensure a seamless and secure experience for your users, making it a great choice for user authentication and password reset processes.
In this tutorial, we'll cover the steps to send OTPs using WASenderAPI in PHP, the benefits of using WhatsApp for OTPs, and how you can enhance the security of your application.
Why Use WhatsApp for Sending OTPs?
WhatsApp is not only one of the most popular messaging platforms globally, but it also provides several advantages when used for sending OTPs. Here’s why WhatsApp OTPs for password recovery are a great choice:
- Instant Delivery: WhatsApp messages are delivered in real-time, ensuring fast OTP delivery.
- Global Reach: With over 2 billion active users worldwide, WhatsApp ensures that your OTPs reach users globally, regardless of their location.
- High User Engagement: People check their WhatsApp messages almost immediately, providing high engagement rates for OTPs.
- Enhanced Security: WhatsApp messages are encrypted, adding an extra layer of security to your OTP delivery process.
- Cost-Effective: Sending OTPs via WhatsApp using an API like WASenderAPI can be more cost-effective than using traditional SMS gateways, especially for international users.
How OTP for Password Recovery Works with WASenderAPI
Integrating OTP for password recovery with WASenderAPI is a straightforward process. Here’s how it works:
- The user requests a password reset by providing their phone number.
- Your PHP backend generates a random OTP.
- You send the OTP to the user's WhatsApp number via WASenderAPI.
- The user receives the OTP on WhatsApp and enters it into your system for verification.
- If the OTP matches, the user can proceed with resetting their password.
With WASenderAPI, the OTP is sent in real-time, ensuring quick recovery for your users while keeping the process secure and user-friendly.
Step 1: Set Up WASenderAPI for OTP Messaging
Before you can start sending OTPs using WhatsApp, you need to set up WASenderAPI. Here's how to get started:
- Sign Up for WASenderAPI: Visit the WASenderAPI website and create an account. After registration, you will receive an API key for authentication.
- Install the API Client: WASenderAPI can be easily integrated into your PHP project using REST API calls. You can send HTTP requests using cURL or any PHP HTTP client.
- Authenticate with Your API Key: Use the API key you received upon registration to authenticate your requests to WASenderAPI and send messages.
After setting up WASenderAPI, you're ready to start sending OTPs to your users via WhatsApp.
Step 2: Generate OTP and Send via WASenderAPI
Now that you’ve set up WASenderAPI, let’s generate a random OTP and send it to your user’s phone number. Here's how you can generate the OTP and send it via WhatsApp in PHP:
Start by generating a random OTP:
function generateOTP($length = 6) { $characters = '0123456789'; $otp = ''; for ($i = 0; $i < $length; $i++) { $otp .= $characters[rand(0, strlen($characters) - 1)]; } return $otp; } // Example usage $otp = generateOTP(); echo "Your OTP is: $otp";
Next, use WASenderAPI to send the OTP to the user’s phone number via WhatsApp. Here’s how you can do it using PHP and cURL:
$phoneNumber = "+1234567890"; // Replace with the user's phone number $otpMessage = "Your OTP for password recovery is: $otp"; // Set your API key here $apiKey = "YOUR_API_KEY"; // cURL request to send OTP via WASenderAPI $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://www.wasenderapi.com/api/send-message"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, [ "Authorization: Bearer $apiKey", "Content-Type: application/json" ]); $data = json_encode([ "to" => $phoneNumber, "text" => $otpMessage ]); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $response = curl_exec($ch); curl_close($ch); // Check the response if ($response) { echo "OTP sent successfully!"; } else { echo "Failed to send OTP."; }
This cURL request sends the generated OTP to the specified phone number using WASenderAPI. The message will be received almost instantly on WhatsApp.
Step 3: Validate OTP for Password Recovery
Once the user receives the OTP, they can enter it in your application to validate their identity. To validate the OTP:
- Store the OTP temporarily in your session or database.
- When the user enters the OTP, compare it with the stored one.
- If the OTP matches, allow the user to proceed with the password reset process.
- If the OTP does not match, prompt the user to try again.
It’s essential to implement a timeout for OTPs to enhance security. For example, OTPs should expire after a set period, such as 5 minutes, to prevent misuse.
