How It Works

Enter a password or generate one.

Browser computes mathematical entropy.

View estimated crack times instantly.

Yes. All calculations happen in your browser using JavaScript. No data is ever sent to our servers.

Entropy is a measure of randomness. Higher entropy means a password is mathematically harder to guess.

We recommend at least 12-16 characters, mixing letters, numbers, and symbols for maximum security.

System Capacity node

Uses advanced zxcvbn algorithms to detect pattern matches, dictionary words, and common exploits.

Calculates real-world estimates for cracking time against modern brute-force hardware.

Your password data never leaves your browser. Analysis happens locally for 100% privacy.

Detects repetitive characters, keyboard sequences, and date patterns that weaken security.

Grades your password from 0 (Weak) to 4 (Very Strong) based on global security standards.

Generate cryptographically secure, high-entropy passwords with a single click.
