Password strength checker
Check how strong a password is. Everything runs locally in your browser—your password is never sent to our servers.
Privacy Built-in: Your password never leaves your device. We use client-side JavaScript for all strength analysis. No server requests are made with your password content.
How it works
Complexity Check
We audit the variety of character types used including case diversity and special symbols.
Entropy Scoring
The longer your password, the higher the entropy, making it exponentially harder to crack.
Dictionary Audit
We cross-reference common words and patterns that are usually the first target for hackers.
