Frequently Asked Questions

What is entropy? ▼
Entropy measures the randomness of a password in bits. Higher entropy = harder to crack. 80+ bits is strong.
Is my password safe here? ▼
Yes. Your password never leaves your browser. All analysis happens locally with no server communication.
How many entropy bits do I need? ▼
For most purposes, 60+ bits is adequate. For high-security applications, aim for 80+ bits. Above 128 bits is considered uncrackable.
