Dahua Password Reset By Serial Number Site

1. The Concept

Dahua devices have a built-in security feature called the "Lock" or "Reset" function. If you enter an incorrect password multiple times (usually 5 times), the device locks you out for a specific duration. To bypass this without losing data, you can use the device's unique Serial Number to generate a temporary reset code.

Free vs. Paid Reset: What to Expect

Free Method (Legitimate)

  • Requires: Proof of ownership (Invoice, business license, original box).
  • Channel: Authorized Dahua Dealer or Tier 2 Support.
  • Time: 24 to 72 hours.
  • Risk: Low. You control the file export.
  1. Required items
  • For many recent Dahua devices, factory reset requires an encrypted token that only Dahua Support or authorized service can generate using the device S/N and a reset GUID shown on the device.
  • Contact Dahua technical support or an authorized dealer with proof of ownership; they will issue a reset token valid for that specific S/N and GUID.
