SparkVault Secure Website Locker gives you full control over which websites can be opened on your
browser by placing them behind a private, local-first authentication screen. Protect pages or entire
domains using a master password, 8-digit PIN, or an offline security key file for emergency recovery.
Each protected site includes custom titles, scopes, and settings, all organized in a clean dashboard
designed for quick access and simple management. Once locked, any attempt to visit a protected page is
instantly redirected to a secure unlock screen that never sends data anywhere. Built to run completely
offline inside your browser’s extension popup, SparkVault ensures a fast, private, and highly structured
way to control access to sensitive sites with confidence.
