Password Generator

Generate strong, random passwords with customizable length, character types, and count.

Weak passwords are the leading cause of account breaches. This password generator creates cryptographically secure random passwords using the Web Crypto API built into your browser. Customize length, character types, and generate up to 20 passwords at once.

All passwords are generated entirely on your device. Nothing is sent to any server or stored anywhere. The tool also estimates password strength based on the character set size and length.

FAQ

Are these passwords truly random?

Yes. The tool uses crypto.getRandomValues(), which is a cryptographically secure random number generator built into modern browsers.

What makes a strong password?

A strong password is long (16+ characters), uses all character types (uppercase, lowercase, digits, symbols), and is randomly generated rather than based on words or patterns.

Are my passwords stored or sent anywhere?

No. Everything runs in your browser. Generated passwords exist only in your browser's memory and are never transmitted.
