Golden Nugget Online Casino uses two-factor authentication (2FA or MFA) to provide an extra layer of security for your online gaming account. 2FA is used in addition to your email address and password and requires you enter a 4- or 6-digit code, depending on the method you choose.

If you choose "Text message", we will send you a unique 4-digit code in a text message to your mobile phone, using the phone number that you registered with:
It is therefore important that the mobile phone number you registered with can receive text messages. If you entered an incorrect phone number, please contact Customer Service to resolve.
If you choose "Authentication App", you will need to use an authentication app you already have installed, or you can install one from a number of vendors, such as:

You will then need to setup an account in the Authentication app.

Here's an example using Twilio Authy:
  • Tap "Add Account"

  • You now have two options: "Scan QR Code" or "Enter key manually".

    If you're signing into Golden Nugget Online Casino on a desktop computer, you can tap "Scan QR Code" to use your mobile phone's camera.

    If you're using your mobile phone to sign in, you'll need to select "Enter key manually" as you won't be able to use your phone's camera.

Desktop ("Scan QR Code"):
  • Point your phone camera at the QR code on screen:

  • Name the account:

Enter the code from the Authentication App (identified in the red box below) into the "Two-Factor Authentication" box on your screen and click "Confirm":

Mobile Phone - if using the same device, you won't be able to use your camera, so instead:

  • Tap "Copy" to copy the code (identified in the red box below):

  • In your Authentication App, find the option to "Enter key manually" (identified in the red box below):

  • Paste the code you copied in an earlier step and save the entry:


Follow any further steps required by your Authenticator app to save the entry.

A code will then be displayed in your Authentication app. Enter the code into the "Two-Factor Authentication" box on your screen:


The Authentication App can then also be used for other sites or services that support 2FA, such as Facebook, Twitter, financial services, etc.
