Two-Factor Authentication (2FA)
Posted by Phil (Netcetera) on 22 February 2018 10:44 AM

Two-factor authentication, also known as 2FA or two-step verification, is an optional feature designed to prevent anyone but you from accessing your Netcetera hosting account by requiring two forms of identity verification: your password and an authentication code. 2FA is ideal for anyone looking to increase their account security because stealing your password isn't enough for a hacker to access your account. They would also need access to your mobile device or email account, depending on how you set it up.

This article explains everything you need to know about two-factor authentication and how you can use it on your account.

How Does It Work?

Once two-factor authentication is enabled, logging in to your account will work a bit differently. You'll enter your Netcetera username and password as usual, and then you'll be prompted to enter a 2FA authentication code which you'll get from an app on your mobile device or your email. Enter the 6-digit single-use code to complete the login process and access your account. Google Authenticator refreshes the code every 30 seconds, but the refresh rate varies per app. Regardless of the refresh rate, each code is valid for 5 minutes.

You'll be prompted to provide an authentication code in three situations:

  • When a login attempt is made.
  • Upon an attempt to enable or disable two-factor authentication.
  • To validate you're an authorized user on an account when you contact one of our support teams for assistance. In this situation, the authentication code is referred to as a validation token.

Mobile Device Setup

Most users prefer to use an authenticator app (like Google Authenticator) on their mobile device to retrieve the code for 2FA. An authenticator app allows you to access the code at any time, even without internet access. After you've installed an authenticator app, follow the steps below to set up 2FA and link your Netcetera account to your device:

  1. Log in to your client area at https://my.netcetea.co.uk
  2. Click the Security menu at the top of the page.
  3. Click Security Settings in the submenu.
  4. Scroll down to Two-Factor Authentication and Click Enable
  5. Use the authenticator app to scan the QR code or manually enter the Secret Key to add your Netcetera account to your device.
  6. Enter the 6-digit code displayed in the app and click Verify Token.

How to Disable Two-factor Authentication

You can disable two-factor authentication by following these steps:

  3. Click Security Settings in the submenu.
  4. Scroll down to Two-Factor Authentication.
