# Account security

### **2 factor authentication**

We use 2FA (two-factor authentication) for all activities and changes in our system. This gives you an additional layer of security.

Please enable 2FA as soon as possilble in menu **Settings\Serurity**

{% hint style="warning" %}
Please keep the access key securely. In case of loss we will not be able to restore it.
{% endhint %}

### **Address book**

The Address Book feature allows users to securely save and manage trusted cryptocurrency wallet addresses for future withdrawals. Before initiating a withdrawal, users can select a previously saved wallet from the Address Book instead of entering the address manually.

### **Sessions**&#x20;

The Session Management feature allows users to monitor and control all active account sessions across different devices and locations. Users can view details such as device type, browser, IP address, login time, and last activity for each session.

For security purposes, users can terminate individual sessions or log out from all devices except the current one. The system may also notify users about new logins, suspicious activity, or access from unknown devices.
