# Security

To enhance user account security, MevX has officially integrated Google Authenticator (2FA) as an added protection layer for critical wallet actions.

## <mark style="color:blue;">What is 2FA on MevX?</mark>

Two-Factor Authentication (2FA) on MevX is a new security feature that replaces the old passcode system. It allows users to bind their trading wallets with Google Authenticator, adding another verification layer before sensitive operations can be completed.

## <mark style="color:blue;">How It Works</mark>

### Binding Google Authenticator

{% embed url="<https://app.arcade.software/share/KyBprlg309NHd5grxxCI>" %}

* Navigate to your Security Settings on MevX.io
* Choose to `Set up 2FA`
* Scan the QR code to install the App
* Scan the QR code using your Google Authenticator app
* Enter the 6-digit verification code to complete the binding process

{% hint style="info" %}
Note: After binding, 2FA will automatically be **enabled**. To disable or unbind it, you will need to input a valid 2FA code.
{% endhint %}

### 2FA Authentication Triggers

* **When 2FA is ON:**
  * All transfers to non-whitelisted wallets will require 2FA input
  * Adding or removing wallets in your whitelist also requires 2FA
* **When 2FA is OFF:**
  * Transfers will proceed normally without additional authentication

{% hint style="info" %}
Disabling 2FA or unbinding Google Authenticator will require you to input the correct 2FA code.

**For your safety, always keep your Google Authenticator backup codes in a secure place. If you lose access to the authenticator app, you may lose access to your wallet functions on MevX.**
