Password Strength Checker & Entropy Analyzer
Analyze the strength of any password locally. Computes entropy bit security, estimated brute-force crack time across modern GPUs, and provides checklist tips for hardening.
Cara Penggunaan
- Type or paste your password into the evaluation field.
- Review the live entropy score, strength grade, and estimated crack duration.
- Verify key security criteria (length, digits, symbols, mixed case).
Pertanyaan Umum
Is it safe to test my real password here?
Yes, 100% client-side computation. No data ever leaves your browser or gets sent over the network.
What is password entropy?
Entropy measures the unpredictability of a password in bits. A score above 60 bits is generally resistant to brute-force attacks.
