How to Use Password Generator
A strong password is your first line of defense against unauthorized access. Our Password Generator uses the Web Crypto API's `crypto.getRandomValues()` function — the same cryptographically secure random number generator used in security-sensitive applications — to create unpredictable, high-entropy passwords. You can customize the length (8–128 characters) and choose which character sets to include: uppercase letters, lowercase letters, digits, and special symbols. Generated passwords are never transmitted or stored anywhere. You can generate as many passwords as you need with a single click.

Frequently Asked Questions
Are the generated passwords truly random?
Yes. They use crypto.getRandomValues(), which is a cryptographically secure pseudo-random number generator (CSPRNG) built into modern browsers.
How long should a secure password be?
A minimum of 16 characters is recommended for most accounts. For critical accounts, use 24+ characters with all character types enabled.
Are passwords stored anywhere?
No. Passwords are generated entirely in your browser and are never transmitted to any server.
