Random Password Generator

This tool creates random passwords from the character sets you enable: lowercase letters are always included, and you can toggle uppercase letters, digits, and symbols on or off. The default is a 16-character password using all four sets.

Randomness comes from your browser's Web Crypto API (crypto.getRandomValues), the same cryptographic source password managers use — not the weaker Math.random function many online generators rely on.

Generation happens entirely on your device. The password is never transmitted, logged, or stored, and a new one is produced every time you adjust a setting or click regenerate.

Human-invented passwords are predictable: names, dates, keyboard walks, and the word 'password' with substitutions. Attackers know every one of these patterns, and breached-password lists make reused passwords a standing liability. Random generation sidesteps all of it.

Length is the biggest lever. Each added character multiplies the search space: a random 8-character password can fall to modern cracking hardware, while a random 16-character password with mixed character sets is effectively uncrackable by brute force. When a site allows it, longer is simply better.

The toggles exist because sites have inconsistent rules — some forbid symbols, others require them. Rather than editing a generated password by hand (which weakens its randomness), switch the sets to match the rules and regenerate.

1. Set your desired length — 16 or more is recommended.

2. Toggle uppercase, numbers, and symbols to match the site's password rules.

3. A new password generates automatically with every change.

4. Copy it and store it in a password manager rather than reusing it elsewhere.

Settings: 16 characters, all character types enabled
