# How WA WorkFlow License Keys Work

When you purchase any **WA WorkFlow** plan, you’ll receive a **license key via email**. This key unlocks full access to all extension features. Here's everything you need to know about how it works:

***

### 📬 <mark style="color:green;">License Delivery</mark>

* Once you complete your purchase, a unique **license key** is sent to your **registered email address**.
* This key is used to **activate premium features** within the extension.

***

### 💻 <mark style="color:green;">Usage Rules</mark>

* Each license key is valid for **one WhatsApp number only**.
* However, you can use the same number on up to **four devices or browser profiles**.

#### 🧠 <mark style="color:green;">Example</mark>

You purchase one license key and activate it on machine **A** with your WhatsApp number. Later, you log in with the **same number** on machines **B**, **C**, and **D** — the license will activate automatically, and all premium features will be available without re-entering the key.

✅ Yes, you can move your license to another number.
