This page is designed to help you find out whether PassInspector is good and if it is the right choice for you.
PassInspector is your first line of defense against weak and compromised credentials. It combines a real-time password strength analyzer, a privacy-safe data breach scanner, and a NIST-approved passphrase generator—all running locally in your browser so no password or passphrase ever touches a server.

Real-Time Password Strength Analyzer:
Your password is analyzed instantly and entirely within your browser using JavaScript. It evaluates length, character variety, common patterns and checks against lists of frequently used passwords, providing an immediate strength rating—with zero data ever transmitted to any server
Privacy-Safe Breach Detection:
Using the "Have I Been Pwned" API with k-anonymity protection, this feature safely checks if your password has appeared in known data breaches. Your password is hashed with SHA-1 locally, and only the first five characters of that hash are sent to the API, ensuring your actual password never leaves your browser and remains fully private
NIST-Compliant Passphrase Generator:
Generate a truly strong yet memorable password with one click. The generator follows NIST SP 800-63B guidelines, randomly selecting four common English words from a list of 1,000 to create a passphrase with over one trillion possible combinations, delivering excellent entropy without sacrificing memorability
PassInspector is unique because every single action—strength analysis, breach scanning, and passphrase generation—happens entirely inside your browser using JavaScript. No password, passphrase, or hash ever leaves your device; the breach check uses k-anonymity so only a small fraction of a non-reversible hash is sent, making it impossible to reconstruct the original password.
A person should choose PassInspector over its competitors because it’s the only tool that combines a real-time strength checker, a privacy-preserving breach scanner, and a NIST-compliant passphrase generator in a single, completely local workflow that requires no registration, no payment, and sends absolutely no sensitive data anywhere.
The primary audience is privacy-conscious individuals, small business owners, IT administrators, and security educators who need a trustworthy, zero-log way to test password strength, check for breaches, and generate strong passphrases without exposing credentials to third-party servers.
The story behind PassInspector stems from a simple frustration: most online password checkers require you to send your password to a remote server, which is a security risk in itself. The creator built PassInspector to prove that robust password hygiene testing can be done with full privacy and transparency, right in the browser.
The primary technologies used for building PassInspector are client-side JavaScript and HTML, the SHA‑1 hashing algorithm for breach checking via the Have I Been Pwned API with k‑anonymity, a local wordlist implementation for NIST SP 800‑63B compliant passphrase generation, and a lightweight UI framework for a fast, responsive experience.
Because PassInspector keeps zero logs and requires no accounts, it does not track or identify individual users. However, it is widely used by small and mid‑sized business IT teams for employee security awareness training, educational institutions teaching digital literacy, and independent security consultants who recommend it as a safe, instant password evaluation tool.
