Dahua Password Reset By Serial Number [verified] -

To reset a Dahua password using a serial number (S/N), you generally need to obtain a temporary security code from Dahua support or use an authorized password generator. Method 1: Dahua Support (Official)

This is the standard procedure for recorders (DVR/NVR) and cameras:

Locate the Serial Number: Find the S/N on the physical sticker at the back/bottom of your device or by clicking the "Forgot Password" link on the login screen.

Note the Date: Take note of the current date and time displayed on the device's screen (OSD), as the security code is date-dependent.

Contact Support: Email the full serial number and the current OSD date to Support.USA@Dahuatech.com or your local regional support.

Enter Temporary Code: Once received, enter the code into the Admin Account field on the device.

Modify Password: Go to Main Menu > System > Account > Modify to set a new permanent password immediately. Method 2: Super Password Generator (Third-Party)

Some users use external tools to generate "Daily Passwords" based on the serial number:

Download Tool: Tools like the CCTV Super Password app (available for Windows/Android) can generate candidate codes.

Generate Code: Enter your serial number exactly as it appears (it is case-sensitive) into the tool.

Test Codes: Try the generated codes (sometimes there are up to five) with the username admin. Method 3: QR Code & DMSS App (Alternative to S/N Only)

If your device shows a QR code on the "Forgot Password" screen, this is often faster than a manual serial number request: Open the DMSS App on your phone. Navigate to Me > Tool Manager > Password Resetting. Scan the QR code on your DVR/NVR monitor.

A security code will be sent to the recovery email address associated with the account. Enter that code on your device to reset the password. Important Tips: FAQ/Password Reset Instructions - DahuaWiki dahua password reset by serial number

To reset a Dahua password by serial number, you can use either a Super Password Generator for older firmware or the official DMSS mobile app for newer systems. How to Find Your Dahua Serial Number (SN)

Before starting, you must locate your device's unique 15-character serial number: Gather required information : You'll need the device's

Physical Label: Check the sticker on the underside or rear of your DVR, NVR, or camera.

On-Screen Menu: If you have local access, right-click and go to Main Menu > Setting > Network > P2P. The SN is typically listed here alongside a QR code.

For most modern Dahua devices (Firmware v4.0 and newer), the serial number is used via the DMSS app to trigger an email-based reset. YouTube·Hik-Connect Hikvision

Method A: Using the Official Dahua ConfigTool (Most Reliable)

This is the preferred method for installers and IT managers.

Step 1: Download and install ConfigTool. Ensure you have version V4.x or higher, as older versions do not support the new encryption algorithms.

Step 2: Launch the tool and locate your device. The tool will automatically scan your local subnet. You will see your locked device listed with a red "Lock" icon.

Step 3: Initiate the "Forgot Password" sequence. Click on the device and select the "Forgot Password" button (sometimes labeled as the key icon).

Step 4: Generate or upload the Serial Number challenge. The tool will present you with a pop-up showing the Device Serial Number. It will ask you how you want to reset the password.

Option A: Send the serial number to your email (if email was configured on the device previously).
Option B: Export a file. This is the "Serial Number Reset" method. Click "Export" to save a .txt or .xml file to your desktop. This file contains the encrypted serial number and timestamp.

Step 5: Obtain the Reset Code (The Security Question). Dahua recently changed their policy (post-2022). You cannot generate the code yourself.

You must send the exported file to your Dahua distributor, your security integrator, or use the official Dahua Support Portal.
Note for end-users: Dahua factory support rarely gives codes directly to consumers due to security policies. They require proof of ownership (invoice matching the serial number).

Step 6: Input the super code. Once you receive the 32-character reset code back from your supplier, paste it into the ConfigTool window. Click "OK." Your password is now reset to "admin" (or a temporary password you set in the tool).

A. The "Unlock Picture" Method (Manual/Support)

Access the Interface: When locked out, the login screen usually displays an option like "Forgot Password" or shows a locked icon.
Generate a QR Code/Picture: The device will display a QR code or a specific "Unlock Picture" on the monitor screen.
Contact Support: You are technically supposed to take a photo of this screen and send it to Dahua Technical Support. They use the information (which contains the serial number and a timestamp) to generate a secure reset file.
Reset: You load this file onto a USB drive, plug it into the device, and the system resets the password to default (usually leaving it blank).

Step 3: Initiate the Reset

Right-click on your locked device or click the padlock icon.
Select "Forgot Password?" or "Password Reset."
A pop-up window will appear asking for the device serial number. Verify this matches your physical sticker.

What If I Don’t Have the Registered Email?

If you are not the original owner or no longer have access to the administrator email, the serial number method will not work for security reasons. In that case:

For installed systems: Contact your security system installer or integrator – they may have a backdoor account or master password.
For second-hand devices: Reach out to the seller to provide the original email or perform the reset before sale.
As a last resort: Perform a hardware factory reset using the physical reset button (varies by model – some require power-cycling while holding the button). Note: This often clears all settings, including network configuration.

C. ConfigTool (Official Software)

If the device is on the same network as a PC, you can use Dahua's official ConfigTool software.

Scan: The tool scans the network and lists all Dahua devices.
Reset: Some versions of the ConfigTool allow you to select the device and click "Reset Password." This often requires a verification code sent to the registered email or a security question if previously set up.
