Professional Analysis

Our tool uses zxcvbn, Dropbox's standard for security measurement. It doesn't just count characters; it detects:

  • Repetitions and sequences (123, abc)
  • Common dictionary words
  • Predictable dates and names

Why a Crack Time?

Knowing if a password is "Strong" isn't enough. The estimated crack time gives you a real perspective of how long your key would resist a modern brute force attack.

If your password takes "centuries" to break, you are safe. If it takes "minutes," change it immediately.

Security Tips

  • Use at least 12-16 characters.
  • Mix uppercase, lowercase, numbers, and symbols.
  • Never use the same password twice.

True Randomness

We use crypto.getRandomValues() instead of Math.random() for maximum cryptographic security.
