This article will show how to reset Dahua DVR (and a wide range of Dahua NVRs) admin password. If you lost or forgot your admin password and no longer can access your DVR, here you can find different methods to recover your lost/forgotten password. The success of these methods depends on the model you have, manufacturing period, firmware version etc. Perhaps the solution for your problem is listed right here. Keep reading these instructions and try it on your Dahua recorder.

Basically, to reset a Dahua DVR/NVR and recover the admin password, you just need to either use a reset button located on the motherboard, try a default password or use a software to generate a new password based on the device date. Let’s go on details about the different methods so you can try to use the one that best suits your needs according to your Dahua DVR/NVR model.

Method 1. Default the password by using the reset button

The success of this method depends on the DVR/NVR model you have, some of them come with a reset button that is located on the motherboard. You just need to open your device to check if that’s your case. See the following pictures that show such button. The reset button should be a black circle and you’ll be able to press it.

Note that in this DVR/NVR model there’s a yellow battery at the right side and a reset button located at the opposite (right) side of the motherboard.

In this model, the yellow battery and the reset button are located on the right side of the motherboard, pretty close to each other. If you can’t find any reset button on your recorder, then your recorders doesn’t have one and you need to try other methods. Dahua started to manufacture built-in reset button on the motherboard by late 2017. Earlier models don’t have a physical reset button.

If you are able to locate the reset button, follow this procedure to reset the Dahua DVR/NVR to factory defaults:
1. Power off the DVR.
2. Press and hold the reset button.
3. Power on the DVR.
4. Keep the reset button pressed for 30 seconds.
5. Create a new password for the admin account.

The process must be done exactly this way. Just make sure you have a monitor attached to the DVR and the power cable is disconnected before starting the process (step 1) and connect the cable while holding the reset button (or you simply use the on/off switch at the back of the Dahua DVR).

You must hold the button until the DVR resets, which will take around 20 to 30 seconds and you will be able to see this information in the monitor. After the reset, the DVR will come back to factory default and ask you to create a new password just like a new installation. See the pictures below.

In the first screen, just create a new password for your DVR by using a minimum of 8 digits with a combination of letters, numbers, and symbols. After creating the password click the “Next” button. The next step is to create the “Unlock Pattern”.

Finally, the last step is to create the security questions just in case you need to reset the password again in the future.

Method 2. Try Dahua default passwords

Sometimes this is the solution. You can try using one of the Dahua default passwords, there are some combination you can try just to see if they work with your device. See the list below for some of these default passwords.

adminadminMaster user
666666666666Guest user
defaultdefaultHidden user

Try on some of these combinations in your Dahua DVR and perhaps you can get access to the device either as admin or as a regular user (if that is enough for your needs).

After this step, the DVR will ask you to create a new password for the user. If this method doesn’t work, or you can get access as a regular user but instead you really need to have admin access, try the next method.

Method 3. Use Dahua password generator

There’s a password generator that can be used to reset the Dahua DVR. You just need to download the software and input the date you see on the monitor. Be careful, the generator will generate a password based on the date you input, if you put the wrong date the generated password will be incorrect.

Type the year, month and day (YYYYMMDD) into the Dahua password generator, and you will get a temporary password, just like shown in the image below:

After generating the temporary password use it to login into your DVR and later just change the password for something else that is better for you. Use the temporary password as the old password.

You can download the Dahua password generator on this link. If this method doesn’t work for you than try the next one.

Method 4. Remove the battery from the motherboard

If your Dahua DVR has a removable battery, you can use this method that is also based on a daily password generator described in the previous method. Remove the battery and wait a little bit (usually 2 minutes) to have the DVR clock back to its default date and time.

The DVR’s date/time stamp usually comes back to 01/01/2000 (default one for this manufacturer). After getting your Dahua DVR clock at this date, try using the following username and password combination: admin (as username) and 668648 (as password) or admin (as username) and 000000000000 (as password). If these combinations doesn’t work for you, try to generate a new password by using the Dahua DVR password generator described previously.

Method 5. Use app DVR password generator

You can download a mobile App to generate a password for your DVR. Look up for the CCTV Super Password and install on your smartphone.

The app shows two different versions of the Dahua password generator, one of them to be used with the DVR date, and the other one that can be used with the DVR serial number. Both of them can generate a temporary password.

Just enter the Day, Month and Year that is shown in your DVR monitor and click submit, so the App returns the temporary password for that specific day.

As you can see in the picture above, there are three options you can try based on the date you entered. Make sure you try to use them on the same day. The next option is to generate a temporary password based o the DVR serial number, just input such number in the aApp and press the Submit button.

The image above shows an example of a temporary password generated by the app, it is meant to be used just one time to get access to your Dahua DVR, so you can create a new one. Remember to also use it on the same day.

Method 6. Call your dealer/seller

This is, in fact, the method we recommend you to try first. If you purchased the Dahua DVR from a local Dahua dealer, give them a call and ask for help to reset the password. Most of the time, this is the fast and easy way to reset the DVR so you won’t spend endless hours trying to recover a lost password and get yourself stressed out.
