Password Strength Meter & Generator
Check how strong your password is, or generate a secure one instantly
Your password is never sent anywhere — all checks happen in your browser.
This tool checks password strength and generates cryptographically random passwords entirely in your browser — nothing is ever sent to a server, logged, or stored. The strength checker evaluates length, character variety, and common weak patterns to give you actionable feedback.
The generator uses crypto.getRandomValues, the same source of randomness used by security software, so generated passwords are genuinely unpredictable. Close the tab and they're gone — no history, no cloud sync, no account needed.
