Strong Password Generator — Safe & Random

Cryptography

What is Strong Password Generator — Safe & Random?

Strong Password Generator is a security utility that creates high-entropy, random passwords locally on your device. In an era of frequent data breaches, using unique and complex passwords for every account is essential. This tool uses the browser's cryptographically secure random number generator (CSPRG) to ensure that your passwords are truly unpredictable and safe from brute-force attacks.

How it works

The tool utilizes `window.crypto.getRandomValues()` to generate random bytes, which are then mapped to your selected character set (letters, numbers, symbols). Because it uses the browser's built-in secure random number generator, the results are much safer than standard `Math.random()`. The generation happens entirely in your browser memory and is never logged or transmitted.

Features & Benefits

  • Generates cryptographically strong random passwords
  • Customizable length and character sets
  • Runs entirely in your browser - no data is sent to any server

Frequently Asked Questions

Is this safe to use?

Yes. The passwords are generated locally using secure browser APIs. We never see or store your passwords.

How long should my password be?

We recommend at least 16 characters for a good balance of security and usability.
