Dahua Dvr — Default Password
If you cannot log in, do not panic. Here are the top four reasons the default password fails.
The Dahua DVR default password (admin/admin) is a necessary evil for setup but a critical vulnerability in production. If you are still using it — or aren’t sure — stop what you’re doing and change it now. Surveillance systems are only as secure as their weakest link, and all too often, that link is a password written on a sticker or left unchanged since installation.
Remember: Security isn’t just about watching. It’s about controlling who watches back.

Dahua DVRs and NVRs traditionally use as both the default username and password. However, the exact credentials vary significantly based on the device's age and firmware version. Common Default Credentials admin / admin does not work, try these widely used factory combinations: Username: admin Password: admin (Most current models). Username: admin Password: 123456 (Common for legacy units pre-2019). Username: 888888 Password: 888888 (High-authority administrator account). Username: 666666 Password: 666666 (Lower-authority user for monitoring and playback). Username: admin Password: 9999@ (Firmware versions v3.1 through v7.x). Username: admin Password: (Leave Blank) (Some OEM variants). Modern Security (Newer Models)
Most Dahua devices manufactured recently no longer have a universal default password. During initial setup, the system forces users to create a unique, strong password. If you are prompted for a password on a brand-new device, it is likely the one set during its first-run initialization. How to Reset if Locked Out

For modern Dahua DVRs and NVRs, there is no universal factory default password. Modern firmware (v6 and newer) forces users to set a unique strong password during the initial setup. Common Default Credentials for Older Models
If you are working with an older or legacy unit, you can try these common manufacturer defaults:
Username: admin | Password: admin (Most common for older units)
Username: admin | Password: 123456 (Common for legacy units pre-2019)
Username: admin | Password: 888888 (Older firmware pre-2017)
Username: admin | Password: 9999@ (Specific to firmware versions 3.1 through 7.x) If you cannot log in, do not panic
Username: 888888 | Password: 888888 (Local administrator account)
Username: 666666 | Password: 666666 (Restricted user account) Recovery Options if Locked Out

Manufacturers include default passwords for one simple reason: ease of installation. When a security professional installs 32 cameras on a network, manually configuring each DVR without a starting point would be a logistical nightmare. The default credential allows initial access to configure network settings, storage, and user permissions.
However, this convenience comes with catastrophic risks if left unchanged.
In legacy firmware (roughly pre-2017), devices shipped with a static, hardcoded administrative credential intended to streamline the initial setup process. Need help resetting a Dahua DVR password

Note: The admin/admin combination remains the most widely known and exploited credential pair in the IoT threat landscape.
Once logged in with default credentials, change the password immediately:
