FAQ
Is generation private?
Yes. Everything runs locally in your browser. Nothing is uploaded.
What length should I use?
At least 12–16 characters for accounts, 20+ for high-value access.
What does entropy mean?
Entropy estimates unpredictability in bits. Higher is better; 80+ is strong, 128+ excellent.
Should I store passwords in a manager?
Yes. Use a reputable password manager and enable 2FA where possible.
