Features and specs

What each product offers, as listed by its team.

PassInspector 3 features
SEMRush 10 features
  • 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

Questions & Answers

As answered by people managing PassInspector and SEMRush.

What makes your product unique?

PassInspector's answer

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.

Why should a person choose your product over its competitors?

PassInspector's answer

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.

How would you describe the primary audience of your product?

PassInspector's answer

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.

What's the story behind your product?

PassInspector's answer

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.

Which are the primary technologies used for building your product?

PassInspector's answer

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.

Who are some of the biggest customers of your product?

PassInspector's answer

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.
