### What is an OTP?

Think of an OTP as a superhero code—it’s:

* **One-time only:** Valid for a single use.
* **Always unique:** A fresh code every time, no repeats!
* **Multi-channel:** Can swoop in via SMS, email, voice call, or an app like <mark style="color:green;">WhatsApp</mark>.

### Ways to Send OTP: SMS, Call, Email, and WhatsApp

Businesses have multiple options for delivering OTPs:

#### 1. SMS:

Sent as a text message to the recipient’s mobile phone.

#### 2. Call:

Delivered via an automated voice call that reads the OTP to the recipient.

* **Pros:** Helpful for users who prefer audio instructions.
* **Cons:** Requires the user to answer the phone, which can delay the process.

#### 3. Email:

Sent to the recipient’s email address.

* **Pros:** Ideal for users without mobile access.
* **Cons:** Requires the recipient to check their inbox, which may cause delays.

#### 4. <mark style="color:green;">WhatsApp</mark>:

Delivered directly to the user’s primary <mark style="color:green;">WhatsApp</mark> device via the WhatsApp Business API.

* **Pros:** Fast, secure, and supported by additional features like verified business accounts and real-time issue resolution.

Sure, traditional OTP methods had their time to shine, but now it’s all about WhatsApp OTP.&#x20;

Here’s why:

#### 1. Better Security:

**WhatsApp OTP**s only show up on the user’s primary device, keeping snoopers at bay.

For added protection, when a user receives a one-time passcode on their primary device, all linked devices display the following message:

*"You received a one-time passcode. For added security, you can only see it on your primary device for WhatsApp."*

This ensures the passcode stays secure and visible only where it’s meant to be.
