400password 3.0

400password by Hikvision

400Password is a legacy, Windows-based support utility developed by Hikvision for authorized service personnel and integrators. It is designed to generate temporary, time-bound recovery credentials for select older Hikvision DVRs, NVRs, and IP cameras when the primary administrator password has been lost. The tool uses device-specific information to produce a one-time code that can help restore access, subject to proper verification, ownership, and local regulations.

Key points:

• Intended users: Authorized Hikvision technicians and trusted partners
• Primary use: Password recovery on legacy models that support the 400-password method
• Platform: Windows; lightweight and typically operates offline
• Compatibility: Not intended for newer firmware and current-generation devices
• Current best practice: For modern products, use Hikvision’s official SADP-based password reset process (XML/QR verification)

Security and compliance:

• Use only with proper authorization and proof of ownership
• Follow all applicable laws, policies, and customer data-protection requirements
• Keep device firmware updated and migrate to supported recovery workflows where possible

Note: Availability and usage of 400Password may be restricted by region and support policy.
