# How to Bind Google Authentication

To maximize the security of your account funds, BitFuFu strongly recommends that every user binds **Google Authentication (Google Authenticator)**. This will provide your account with a second layer of protection in addition to your login password.

### **Preparation**
Before starting the binding process, please install **Google Authenticator** on your mobile phone:
* **Android Users:** Search for "Google Authenticator" in the Google Play Store to download and install it.
* **iOS Users:** Search for "Google Authenticator" in the App Store to download and install it.

### **Binding Process**
* **1.Enter Account Settings:** Log in to the BitFuFu official website, click on **"Dashboard"** in the upper right corner, and enter the **"Settings"** page. ![](https://storage.crisp.chat/users/helpdesk/website/-/6/d/a/5/6da5b5c64a4c4000/image_x3ekty.png)

* **3.Get Secret Key / QR Code:**
    * The page will display a **QR Code** and a **16-digit secret key**.
    * **Important Note:** Please be sure to back up this secret key in a safe place (such as writing it down on paper). If your phone is lost, this secret key is the only credential to recover your authenticator.

* **4.Add Account in the App:**
    * Open the **Google Authenticator App** on your phone.
    * Tap the **"+"** icon in the bottom right corner, and choose **"Scan a QR code"** or **"Enter a setup key"**.
    * *Once successfully added, a 6-digit dynamic code labeled "BitFuFu" will appear in the App.*
* **5.Complete Verification:**
* Return to the BitFuFu binding page.Enter your email/mobile verification code, along with the current **6-digit Google verification code** displayed in the App.Click **"Open Google Authentication"** to complete the setup. ![](https://storage.crisp.chat/users/helpdesk/website/-/6/d/a/5/6da5b5c64a4c4000/image_o6p48e.png)
 
### Precautions
* **Time Synchronization:** Google verification codes are generated based on time. If you receive a "verification code error," please check whether your phone's time is synchronized with internet time (the discrepancy must be within 30 seconds).
* **Do Not Uninstall the App:** Before unbinding Google Authentication, do not uninstall the authenticator App at will, otherwise you will be unable to log into your account.
* **Multiple Protection:** It is recommended to bind both your phone number and email at the same time for secure recovery in extreme situations.
