# TOTP

## Requirements

* **Linux Control Center**: version **2.12.X** or higher
* **TOTP Authentication Application** (such as Google Authenticator, Authy, etc.)

***

## Overview

The **Linux Control Center (LCC)** allows you to configure two-factor authentication (2FA) through a TOTP application. This functionality increases security when accessing the Management Console.

## Objective

This document aims to guide the process of enabling 2FA in user accounts with access to the LCC Console.

## How to Enable TOTP in an LCC Access Account

1. Access the **LCC** and click on **Config** in the left side menu.

> **hint:** To disable TOTP, simply click on the **TOTP** option again and enter your username and password to confirm the operation.

1. After saving the code, simply log in normally using your enabled authentication method and then the six-digit code.

## Additional Tips

* Keep the recovery code, if provided, in a safe place.
* If you lose your authenticator device, contact your system administrator to reset 2FA authentication or, if you are logged in, reset the TOTP configuration for your user.
