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.
Your Secrets are Safe
100% Client-Side
Code runs on your device. The password never travels over the internet.
True Randomness
We use crypto.getRandomValues() instead
of Math.random() for maximum cryptographic
security.
Mobile Design
Optimized so you can generate quick passwords from your phone.
