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
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

Device Initialization and Password Reset for Networking Cameras
Historically, Dahua devices shipped with a set of default accounts, each with its own permission level. However, newer models (manufactured within the last several years) typically do not have a default password; they require the user to initialize a strong password upon the first startup. Default Password Role / Access Level admin Master account (full system access) 888888 Local Administrator account 666666 Restricted User default Hidden / Basic User admin Common on some OEM/Legacy models Password Reset & Recovery Methods
If the default credentials do not work and you cannot access the system, use these official recovery methods:
Security Questions: If configured during initialization, you can answer three security questions via the "Forgot Password" link on the login screen to set a new password. Dahua DVRs manufactured before 2017 typically use the
DMSS Mobile App: Open the DMSS app, go to Me > Tool Manager > Device Password Management, and scan the QR code displayed on the DVR's local monitor to receive a reset code via email.
Physical Reset Button: Many newer Dahua DVRs and NVRs feature a physical reset button on the motherboard. Disconnect the power, hold the button for 10–30 seconds while reconnecting power, and wait for the system to beep or reboot to factory settings.
Jumper Reset: For older models without a button, look for two pins on the motherboard labeled "Reset" or "J1/J2." Shorting these pins with a jumper or tweezers while powering on can trigger a factory reset. Security Recommendation
To prevent unauthorized access, security experts recommend changing the default password immediately after installation and updating it every three months.
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.
Everything You Need to Know About Dahua DVR Default Passwords
If you have just installed a new security system or are trying to log into an older recorder, finding the Dahua DVR default password is likely your first priority. Security hardware manufacturers have changed their approach to default credentials significantly over the last few years to improve cybersecurity.
This guide covers the common default credentials for Dahua devices, how the login process has changed, and what to do if you are locked out. What is the Default Password for Dahua DVRs?
For older Dahua models (typically manufactured before 2017), the factory default login credentials were standardized across almost all units. Common Legacy Credentials: Username: admin / Password: admin Never leave defaults in place
Username: admin / Password: 888888 (This is often the "local" admin account) Username: 666666 / Password: 666666 (Limited user account)
Note: On many older systems, if the password "admin" doesn't work, try leaving the password field blank. The Shift to Initialized Security
In newer Dahua firmware versions, there is no longer a universal default password. When you boot up a modern Dahua DVR or NVR for the first time, the system will force you to "initialize" the device. During initialization, you are required to: Set a custom admin password. Provide an email address for password recovery. Set security questions.
This change was implemented to prevent "botnet" attacks where hackers scan the internet for devices using well-known factory defaults. How to Reset a Forgotten Dahua Password
If the common defaults don’t work and you don't remember the password you set during setup, you have several recovery options: 1. The Reset Button
Most modern Dahua DVRs have a physical reset button on the motherboard. Power off the unit. Hold down the reset button.
Power the unit back on while continuing to hold the button for 30 seconds.
The device should reboot into its factory-fresh "uninitialized" state. 2. Using the XML File Method
If you use the ConfigTool software on a computer connected to the same network: Open ConfigTool and find your device. Click "Reset Password."
Export the XML file and send it to your Dahua distributor or technical support.
They will send back an XML file that allows you to create a new password. 3. Security Questions or Email Recovery
If you set up an email or security questions during initialization:
On the DVR login screen, click the "Forgot Password" icon (it looks like a key or a question mark).
Follow the prompts to receive a security code via email or answer your pre-set questions to unlock the system. Security Best Practices
Once you regain access to your DVR, keep these tips in mind to stay secure:
Change Default Ports: Change the default HTTP port (80) and TCP port (37777) to something unique.
Update Firmware: Regularly check the Dahua website for firmware updates that patch security vulnerabilities.
Disable Unused Accounts: Delete or disable the "666666" or "888888" accounts if your firmware allows it.
