Enhancing Synology NAS Security with Two-Factor Authentication (2FA)


Securing your data is crucial, especially when using Network Attached Storage (NAS) devices to store sensitive information. Synology NAS systems offer a range of security features, including Two-Factor Authentication (2FA), which adds an extra layer of protection to your NAS. In this article, we will guide you through the process of setting up 2FA on your Synology NAS. Additionally, we will provide a reference to our articles comparing Seagate IronWolf and WD Red HDDs and a comparison of Synology NAS models to help you make an informed decision when selecting your storage solution.

Step 1: Enable 2FA on Your Synology NAS To enable 2FA on your Synology NAS, follow these steps:

  1. Log in to your Synology NAS web interface using your credentials.
  2. Click on the main menu and then select “Control Panel.”
  3. Under the “Security” tab, click on “Account.”
  4. Check the box next to “Enable 2-step verification” and click “Next.”

Step 2: Set Up an Authenticator App To use 2FA, you will need an authenticator app on your smartphone or tablet. Some popular options include Google Authenticator, Authy, and Microsoft Authenticator. Download and install your preferred authenticator app before proceeding.

Step 3: Scan the QR Code and Configure 2FA After enabling 2FA on your Synology NAS and installing an authenticator app, follow these steps:

  1. On the “Step 1: Set up a verification app” screen, use your authenticator app to scan the QR code displayed on the screen.
  2. Your authenticator app will generate a 6-digit verification code. Enter the code in the “Verification code” field on your Synology NAS and click “Next.”

Step 4: Save the Backup Codes After setting up 2FA, you will be provided with a set of backup codes. These codes can be used to access your Synology NAS in case you lose your authentication device or cannot generate a verification code. Save these backup codes in a secure location, such as a password manager or a safe deposit box.

Step 5: Test 2FA on Your Synology NAS Once you have completed the setup process, log out of your Synology NAS and log back in. You will be prompted to enter a verification code generated by your authenticator app. Enter the code to confirm that 2FA is working correctly.


Setting up 2FA on your Synology NAS is a crucial step in enhancing the security of your data. By following this guide, you can ensure that your Synology NAS is protected by an additional layer of authentication. While securing your NAS is essential, it’s also crucial to choose the right storage solution. Our articles on the differences between Seagate IronWolf and WD Red HDDs, as well as a comprehensive comparison of various Synology NAS models, can provide valuable insights to help you make an informed decision for your storage needs.
