Google Authenticator

Google Double Factor Authenticator or Google 2FA is a module that adds an extra layer of security to NexoPOS 4.x accounts. By default, the feature is disabled for every user, but it can be enabled by using the Google Authenticator app and scanning the QR Code.

This module is compatible with NexoPOS 4.3.2 and above.

Module Installation

This module can be installed as any other module. You can follow the tutorial that explains how to install NexoPOS modules.

Enable 2FA for an account

Once the module is enabled, we'll need to access the profile to set up 2FA.

From the profile, we'll need to click on "Google 2FA" to see the QR Code that we need to scan.

As a reminder, you can use the Google Authenticator app available on Play Store if you're using an Android device. If you're using an iPhone, you can also use the same app on the App Store.

First of all, you'll scan the code, and that will register your account on the app. After scanning, you'll see a new entry on the Google Authenticator app with a code. That code should be added to the "Validation" section, then press "Validate".

Disabling 2FA

Once the account has 2FA enabled, you'll be able to disable it from your profile.

Disable the 2FA For An Account

As an administrator, the Google Authenticator modules allow you to disable the 2FA feature. You'll need to head to the users and open the options for the account you would like to disable the Two-Factor Authentication.

You'll be asked to confirm your action.

How It Works

Once 2FA is enabled on your account, you'll be asked to provide a code every time you log in to the system. After successful authentication, you'll be redirected to provide the 2FA code.
