Introduction

Two-Factor Authentication (2FA) is the most secure way to protect your Nexcess account. Instead of relying solely on a password, 2FA requires two factors for access: your password, plus a unique code sent instantly to your registered phone number via text message (SMS). This setup effectively blocks unauthorized access because a hacker would need both your password and your physical phone.

Prerequisites

  • A Nexcess account.
  • A valid cell phone number.

Step-by-Step Instructions

Enable SMS Authentication

Use the following instructions to enable two-factor authentication for your my.nexcess.net account.

  1. Log in to my.nexcess.net.
  2. From the drop down list, select Team. 
  3. Locate your user name, then click the edit (pencil) icon.
  4. From the Country Code drop-down list, select your country. In the Cell Phone field, enter your area code and phone number.
  5. Click Save.

Authenticating with SMS

  1. Log in to my.nexcess.net.
  2. Click the Send SMS Code button. (A message will be sent to the phone number on record. Standard messaging rates may apply.)
  3. Enter the six-digit code into Authentication Code field in the Log In page.
  4. If desired, select the Remember this device for 30 days check box.

  5. Click Log In.

Frequently Asked Questions (FAQs)

There are two common reasons for delay:

  1. Check Mobile Signal: Ensure your phone has a strong mobile signal.
  2. Wait Briefly: Allow at least 60 seconds before clicking the “Resend Code” button. Network delivery can sometimes be delayed depending on your carrier.

This is critical. If you lose access to your phone, you must contact our Support team immediately to have SMS authentication manually disabled on your account. We will verify your identity, and once confirmed, we will remove SMS authentication so you can log in again. You should then set up the service immediately with your new phone number.

Nexcess does not charge for this feature. However, standard messaging rates from your mobile carrier may apply for receiving the SMS codes.
