Understanding Why You Might Need to Reset Your Dahua NVR Password
Before we jump into the "how-to," it's helpful to recognize the common reasons users seek to reset Dahua NVR password. Understanding these scenarios can help prevent future lockout situations and reinforce good security practices:
- Forgotten Password: This is by far the most common reason. With numerous passwords to remember in our daily lives, it’s easy to forget a less frequently used one like your NVR’s.
- Inherited System: If you've purchased a property with an existing Dahua NVR or taken over system management, you might not have been provided with the correct credentials.
- Default Password Issues: Sometimes, the system might revert to a default password, or you might be trying to log in with an old default that was never changed (a significant security risk!).
- Security Best Practices: Regularly changing your password or needing to update it after a security audit might necessitate a reset if the old one is no longer accessible.
According to a report by Varonis, over 60% of all data breaches are caused by weak or stolen credentials. This highlights the critical importance of proper password management and knowing how to securely recover Dahua NVR password when needed.
| Reset Method | Complexity/Effort | Typical Scenario | Estimated Time |
|---|---|---|---|
| Forgot Password (GUI via Monitor/QR Code) | Low | Modern NVR with monitor/internet access; user has DMSS/ConfigTool installed. | 2-5 minutes |
| ConfigTool / SmartPSS / DMSS App (Security Code) | Medium | NVR on same network as PC/phone, no direct internet on NVR, or QR fails; requires Dahua support/dealer. | 5-15 minutes (excluding support wait time) |
| Hardware Reset (Internal Jumper/Button) | High (requires opening NVR) | Older NVR models without software reset, all other methods failed, unit completely inaccessible. | 15-30 minutes (disassembly & reassembly) |
Method 1: The Modern Way – Using Dahua ConfigTool (for Newer NVRs)
For most modern Dahua NVRs, the ConfigTool offers a streamlined and secure way to perform a Dahua NVR password reset without losing recorded data. This method relies on a challenge-response system.

Prerequisites:
- Your Dahua NVR must be connected to the same local network as your computer.
- You need to have the latest version of Dahua ConfigTool installed on your PC.
- Internet access (sometimes required for generating codes).
Step-by-Step Guide:
- Launch ConfigTool: Open the Dahua ConfigTool. It will automatically scan your local network for Dahua devices.
- Locate Your NVR: Find your NVR in the device list. It will typically show its IP address, model, and current status.
- Initiate Password Reset: Select your NVR and click the "Forgot Password" button (usually represented by a question mark icon or similar).
- Choose Reset Method:
- Security Questions: If you previously configured security questions, you can answer them here to set a new password.
- QR Code Method (Recommended): A pop-up will display a QR code. Use your Dahua DMSS mobile app (or another QR scanner app) to scan this code. The app will generate a "Security Code" or "Safe Code" for you.
- XML Export Method (Older Firmware/Specific Models): Some NVRs will allow you to export an XML file. You'll need to send this file to Dahua technical support or your dealer, who can then provide an encrypted XML file or a temporary "super password" to decrypt it.
- Enter Security Code/Super Password: Input the code generated by your app or provided by Dahua support into the ConfigTool window.
- Set New Password: Once authenticated, you will be prompted to create a new, strong password for your Dahua NVR. Confirm it and click "Next" or "OK."
- Login: Your Dahua NVR admin password has now been reset. You can log in with your new credentials.
Method 2: Manual Reset via Security Questions (Older Firmware / Direct NVR Access)
For older Dahua NVR models or if you configured security questions directly on the NVR interface, this method offers a straightforward way to reset Dahua NVR admin password.

Accessing the Password Reset Interface:
- Connect a monitor directly to your Dahua NVR.
- At the login screen, attempt to log in. After a few incorrect attempts, or by explicitly clicking a "Forgot Password" link on the interface, you should be prompted with options.
Step-by-Step Guide:
- Select "Forgot Password": On the NVR's login screen, click the "Forgot Password" or similar option.
- Answer Security Questions: If this option is available and you previously set them up, you will be presented with the security questions you configured (e.g., "What is your mother's maiden name?", "What was your first pet's name?").
- Provide Correct Answers: Accurately answer the questions.
- Set New Password: If your answers are correct, the system will allow you to create a new admin password. Choose a strong, memorable one.
- Confirm and Apply: Confirm the new password and apply the changes. You should now be able to log in.
This method is highly dependent on prior setup and can be the quickest if those questions are known.
Method 3: Hardware Reset / Factory Default (The Last Resort)
When all other software-based methods to reset Dahua NVR admin password fail, a hardware reset might be your only option. Be aware that this process will erase all configurations and settings, returning the NVR to its factory default state. Recorded footage is generally preserved, but user accounts, network settings, and recording schedules will be wiped.
When to Consider a Hardware Reset:
- You've tried software methods without success.
- You don't have access to Dahua ConfigTool or support.
- A complete system reset is acceptable, and you can easily reconfigure the NVR.
The Process:
- Locate the Reset Button:
- For many Dahua NVR models, the reset button is located on the main circuit board inside the NVR casing. You'll need to open the NVR to access it.
- Some newer or smaller NVRs might have an external pinhole reset button. Consult your NVR's manual for its exact location.
- Power Off the NVR: Disconnect the NVR from its power source.
- Press and Hold the Reset Button: While the NVR is powered off, press and hold the reset button.
- Power On While Holding: Reconnect the power cable to the NVR while continuously holding down the reset button.
- Continue Holding: Keep holding the button for approximately 10-30 seconds. You might hear beeps or see LED indicators change, signaling the reset.
- Release the Button: Once you've held it for the recommended time, release the button.
- Initial Setup: The NVR will boot up in its factory default state. You will likely be prompted to create a new admin password and configure all initial settings, including network and recording preferences. The default username is typically "admin."
Always double-check your specific NVR model's manual for the precise hardware Dahua NVR factory reset procedure, as it can vary slightly between models.
Important Considerations and Best Practices After Resetting Your Password
Successfully performing a Dahua NVR password reset is only half the battle. To maintain robust security and prevent future lockouts, follow these essential best practices:
- Set a Strong, Unique Password: Never use easily guessable passwords like "123456" or "admin." Opt for a complex combination of uppercase and lowercase letters, numbers, and symbols.
- Enable Security Questions: Immediately configure security questions on your NVR. This provides a convenient recovery option for future password issues.
- Record Your Credentials Securely: Keep a record of your username and password in a secure location, such as a password manager or a physically secure vault.
- Regularly Update Firmware: Ensure your Dahua NVR's firmware is always up-to-date. Firmware updates often include critical security patches and improved functionality for Dahua NVR password recovery.
- Change Default Port Numbers: If your NVR is accessible from the internet, change its default HTTP (80) and TCP (37777) port numbers to random, non-standard ones. This significantly reduces the risk of brute-force attacks.
- Network Security: Ensure your network is secure. Use a strong Wi-Fi password and consider isolating your surveillance network from your main network if possible.
Neglecting these steps after you reset Dahua NVR admin password can leave your system vulnerable to unauthorized access, potentially compromising your security footage and privacy.
Conclusion
Forgetting your Dahua NVR admin password can be a stressful experience, but as you've seen, there are multiple reliable methods to regain access. Whether you leverage the modern capabilities of Dahua ConfigTool, utilize pre-configured security questions, or resort to a hardware factory reset, regaining control of your security system is achievable.
Remember, the goal isn't just to get back in, but to ensure you stay secure. By implementing strong password practices and following the recommended security tips, you can protect your surveillance system effectively. Don't let a forgotten password compromise your peace of mind or the integrity of your security setup.

Frequently Asked Questions
I forgot my Dahua NVR admin password. How can I reset it?
If you've forgotten your Dahua NVR admin password, the most common and recommended method involves using the Dahua ConfigTool software on a PC to export an XML file and generate a reset code. This process usually requires contacting Dahua support or your vendor to provide the reset code. For some very old NVR models, a physical reset button might be accessible on the motherboard for a full factory reset.
What tools or software do I need to reset my Dahua NVR password?
To effectively reset your Dahua NVR admin password, you will primarily need the Dahua ConfigTool software installed on a Windows PC. Ensure your PC is connected to the same local area network (LAN) as your Dahua NVR to allow the ConfigTool to discover and communicate with the device. You may also need access to the internet to send the generated XML file for a reset code.
Can I reset my Dahua NVR admin password remotely, without physical access to the device?
Yes, you can often reset your Dahua NVR admin password remotely if your PC is on the same local area network (LAN) as the NVR. The Dahua ConfigTool software communicates with the NVR over the network to facilitate the password reset process without needing direct physical interaction. However, if you are on a completely different network, you would need prior remote access configured or physical presence.
The Dahua ConfigTool method isn't working for my NVR. What else can I try?
If the ConfigTool method isn't detecting your NVR or generating a valid reset code, first ensure your NVR's firmware is up to date and your network connection is stable. For some specific or very old models, a physical reset button might be present on the main board, which typically requires opening the NVR's casing. If all troubleshooting fails, it's best to contact Dahua technical support or your product vendor for specialized assistance.
Will resetting the Dahua NVR admin password erase my recordings or change other settings?
Generally, resetting only the Dahua NVR admin password using the ConfigTool software will not erase your recordings or modify other existing system configurations. This method specifically targets the password credentials to regain access. However, performing a full factory reset (if available on your model) will wipe all settings and revert the NVR to its default state, which could include formatting the hard drive and deleting recordings.
Is there a default admin password for Dahua NVRs I can try?
For older Dahua NVR models, common default admin passwords included "admin" or "888888". However, newer Dahua NVRs require you to set up a unique, strong password during the initial activation process when the device is first powered on. This means there is no universal default password for freshly installed or activated modern Dahua NVRs, and you must use the password you configured.
