Many users often do not change the default account password after installing and using monitoring products, mainly to avoid the trouble of remembering the password. However, doing so will make your surveillance product vulnerable to cyber attacks, and anyone can access the device by knowing the device’s default password. Therefore, when using monitoring equipment, users should modify the default password in time. However, after installing the device for a long time without logging into the device for configuration, there is no doubt that the user will forget the password.

If you use Dahua DVR recorder and forget the login password, the best way is to contact Dahua’s official website after the sale. They will use the software to generate a temporary password based on the time displayed on your DVR. The temporary password will be one day Valid within. The user should change the DVR password immediately after logging in to the DVR with the temporary password.
