Dahua Dvr Default Password May 2026

Once you gain access using the default credentials, the first and only action you should take is changing the password. Here is the standard path:

For security auditors and administrators managing Dahua infrastructure:

Older Dahua DVR models typically use default credentials of username "admin" and password "admin" or "123456". Newer devices require initialization and a custom password, though if locked out, methods like scanning a QR code via the DMSS app, utilizing a hardware reset button, or using the Dahua ConfigTool for XML-based recovery can be used. For a comprehensive, official guide on device initialization and password recovery, refer to the document at dahuasecurity.com Dahua DVR: Default Login Credentials & Password Reset

The most common default username and password combinations for Dahua DVRs are: * Username: admin. * Password: admin or 123456.

The default credentials for most modern Dahua DVRs and NVRs are admin / admin. However, the exact password depends significantly on the unit's age and firmware version. Common Default Credentials Notes / When to Use admin admin Primary default for most current models. admin 123456 Common for legacy firmware (pre-2019 units). admin 9999@ Used in firmware versions 3.1 through 7.x. admin 888888 Older Dahua firmware (pre-2017). admin (blank) Some OEM variants—try submitting an empty field. Firmware-Specific Behavior

Firmware v6.x and v7.x: These versions enforce mandatory password creation upon first login. There is no universal factory default; the device must be initialized by the user.

Firmware v4.x and v5.x: Default is often 9999@, but the "User Account" mode must be enabled for the password to be accepted. Recovery and Reset Methods

If the default passwords do not work, you can regain access through several recovery options:

QR Code Recovery: On newer models, click "Forgot Password" on the login screen to generate a QR code. Scan this with the DMSS Mobile App to receive a temporary reset code via your registered email.

Hardware Reset Button: Many units have a physical reset button on the motherboard. Power off the device, press and hold the button, then power it back on and hold for 10-15 seconds until a beep sounds to return settings to factory defaults.

CMOS Battery Removal: For older units without a reset button, removing the CR2032 coin-cell battery for at least 60 seconds can reset the system clock and potentially revert the password to admin / 668648 or admin / 000000000000.

ConfigTool: You can download the Dahua ConfigTool to export an XML file for your device and send it to an authorized dealer for a remote unlock code. dahua dvr default password

The Ultimate Guide to Dahua DVR Default Passwords and Recovery

For security professionals and homeowners alike, losing access to a Dahua DVR is a common but frustrating hurdle. Whether you are performing a fresh installation or recovering an older system, knowing the correct Dahua DVR default password is the first step toward regaining control. 1. Common Dahua DVR Default Password Combinations

Depending on the manufacturing date and firmware version of your Dahua unit, the default credentials will vary. Default Password admin admin Most common for current and standard models. admin 123456 Common for legacy firmware (pre-2019 units). admin 888888 Typically found on units manufactured before 2017. 888888 888888 Local administrator account for older units. 666666 666666 Restricted user account (monitor/playback only). admin 9999@ Specific to firmware versions 3.1 through 7.x. default default Hidden user account for internal system use.

Note: For newer Dahua devices, there is often no "factory" default password. During the initial setup, the system will force you to create a unique, strong password. 2. Default Pattern Lock

Many modern Dahua DVRs use a pattern lock instead of a traditional text password for local access. If you are prompted for a pattern on a new or reset device, the default is often the shape of a capital "L" connecting the dots. 3. How to Reset a Forgotten Dahua Password

If the standard defaults do not work, you can use several recovery methods that do not necessarily erase your video recordings. A. Using the "Forgot Password" QR Code

This is the fastest method for units running firmware v6.x or v7.x. Click Forgot Password on the login screen. Open the DMSS app on your smartphone. Navigate to Me > Tool Manager > Device Password Management. Scan the QR code displayed on the DVR monitor.

A security code will be sent to your registered recovery email. Enter this code on the DVR to set a new password. B. Daily Password Generator

For older firmware that doesn't support QR codes, you can use a "Daily Password" based on the system date. Note the exact date and time displayed on the DVR monitor. Use a free Dahua Daily Password Generator online.

Enter the date in YYYYMMDD format to get a temporary master password. C. Hardware Reset Button

If you cannot access the software menus, many Dahua motherboards have a physical reset button.

What Is Dahua Default Password And How to Keep Passwords Securely Once you gain access using the default credentials,

So you’re locked out of your Dahua DVR—or maybe you just finished setting it up and realized "admin/admin" isn't working like the old days. Here is the lowdown on getting back in and why things have changed. The "Big Three" Classics

If you are working with an older or uninitialized device, start with these usual suspects: The "Sixes": Some specific models use for basic local access. Why "admin" Might Not Work Anymore

Modern Dahua devices prioritize security. On the first boot, you are now often forced to initialize

the device by creating a custom, strong password. If you bought a used DVR or forgot that initial setup password, the "default" literally no longer exists. Emergency: The "I'm Stuck" Survival Guide

If the classics fail, don't panic. You have three main escape routes: The Physical Reset: Look inside the DVR casing. Most newer units have a small Reset Button

on the motherboard. Hold it for 10–15 seconds while powering on to revert all settings to factory default. The "Tweezer" Trick:

For older models without a physical button, look for two small holes labeled

(often near the battery). Short-circuiting these pins with a pair of tweezers for a few seconds during boot-up can trigger a reset. The QR Code Reset:

If you set up a recovery email during initialization, click the "Forgot Password" icon on the login screen. It will generate a QR code you can scan with the DMSS mobile app to receive a temporary security code. Quick Tip: Once you're back in, immediately set up your Security Questions

For most current Dahua DVR models, there is no single default password because the system enforces mandatory password creation during the initial setup. However, if you are working with an older or legacy unit, you can try several common factory-set combinations. Common Default Credentials

If your device has not been initialized or is a legacy model, try these username and password pairs: Older Dahua DVR models typically use default credentials

Username: admin / Password: admin (Most common for cameras and older recorders)

Username: 888888 / Password: 888888 (Common administrator account for older local access)

Username: 666666 / Password: 666666 (Restricted user for monitor and playback only)

Username: admin / Password: 123456 (Found in some legacy firmware versions)

Default Pattern: On many newer touchscreen or mouse-controlled interfaces, the default unlock pattern is a capital "L" shape. Recovery Options if Defaults Fail

If the above credentials do not work, it means a custom password was set. You can use these methods to regain access:

Dahua devices have a known security vulnerability/feature: a backdoor algorithm that generates a unique reset password based on the device’s serial number and the current date. Several third-party tools (e.g., "Dahua Password Resetter" or "DahuaConfigTool") can generate a temporary password.

Because Dahua manufactures for third parties, here is a quick cheat sheet:

Using default passwords for anything other than initial setup and immediate password change is highly insecure. Default passwords are widely known and can be easily exploited by unauthorized individuals to gain access to your device and potentially your network.

Look at the bottom or rear panel of the DVR. Some models include a sticker with a unique "QR Code" or "Device Initialization Password." This is not the universal default but a unique, machine-specific password.
