Password Strength Checker
Analyze password strength locally with entropy, crack-time estimates, character-set details, warnings, and practical suggestions.
Best For
Use Password Strength Checker when you need to inspect, convert, compare, or package technical material quickly. The page is designed around a focused workflow: bring in the code, data, markup, URL, or technical file, make the adjustment or check, then copy or download the result for your repo, ticket, documentation, or handoff.
Most work happens locally in your browser, which keeps files and text on your device and makes quick repeat checks practical. Review the output, then copy or download the result for your repo, ticket, documentation, or handoff.

Features
Local Analysis
The password is analyzed in your browser, keeping the check private while you review the result.
Crack-Time Estimate
Estimate brute-force resistance from length, character set size, and entropy.
Practical Suggestions
See targeted warnings for short length, missing character classes, repeated runs, and common patterns.
How It Works
Type or paste the password you want to inspect.
Check entropy, charset size, estimated crack time, and strength label.
Use the suggestions to make the password longer and less predictable.
