Frequently Asked Questions

How secure is this password generator?

This password generator uses your browser's built-in cryptographic randomness (crypto.getRandomValues) to produce truly unpredictable passwords. No data is ever sent to a server — everything runs locally in your browser, ensuring your passwords are never transmitted or stored anywhere.

Are passwords saved or stored anywhere?

No. Passwords are generated entirely in your browser and are never sent to any server. The session history only keeps the last 5 passwords temporarily in your browser's memory and is cleared when you close the tab or click the clear button.

What makes a strong password?

A strong password is long (12+ characters), uses a mix of uppercase letters, lowercase letters, numbers, and symbols, and avoids common words or patterns. Our strength indicator evaluates your settings in real time so you can adjust for maximum security.

Can I use this for Wi-Fi passwords?

Yes. Wi-Fi passwords typically need to be 8–63 characters and can include letters, numbers, and some symbols. Our generator lets you customize the length and character types to match your router's requirements perfectly.
