Password Generator: Create Strong Passwords Instantly

Why Random Passwords Matter

Humans are terrible at creating random passwords. We use pet names, birthdays, keyboard patterns (qwerty, 123456), and common substitutions (p@ssw0rd). Attackers know all of these tricks. A truly random password with sufficient length is the only reliable defense.

A 16-character password using uppercase, lowercase, numbers, and symbols has approximately 10³⁰ possible combinations. At one trillion guesses per second, that would take longer than the age of the universe to crack by brute force.

Customization Options

• Length — Choose anywhere from 4 to 128 characters. We recommend 16+ for most accounts.
• Uppercase letters (A–Z) — Toggle on/off.
• Lowercase letters (a–z) — Toggle on/off.
• Numbers (0–9) — Toggle on/off.
• Symbols (!@#$%^&*) — Toggle on/off. Some sites restrict certain symbols.

A strength meter shows you the estimated security level in real time as you adjust settings.

Pro tip: For maximum security, keep all character types enabled and use at least 16 characters. If a website doesn't allow symbols, turn them off but increase the length to compensate.

How to Use

1. Open the Password Generator
2. Adjust the length slider (default: 16 characters)
3. Toggle character types as needed
4. A new password generates instantly with every change
5. Click "Copy" to copy to clipboard
6. Click the refresh button to generate a new password with the same settings

Password Strength Guidelines

• Weak (<8 chars) — Can be cracked in seconds. Never use for anything important.
• Fair (8–11 chars) — Better, but vulnerable to targeted attacks.
• Strong (12–15 chars) — Good for most accounts.
• Very Strong (16+ chars) — Excellent. Use for banking, email, and critical accounts.

Best Practices

• Never reuse passwords — If one site is breached, every account with that password is compromised.
• Use a password manager — You only need to remember one master password. The manager handles the rest.
• Enable two-factor authentication (2FA) — Even if your password leaks, 2FA adds a second barrier.
• Change compromised passwords immediately — Check Have I Been Pwned to see if your email has appeared in a data breach.

How Randomness Works

Our generator uses the browser's built-in crypto.getRandomValues() API, which produces cryptographically secure random numbers. This is the same randomness source used by encryption libraries and security software — not the weaker Math.random() that many basic generators use.

Privacy

Your passwords are generated entirely in your browser. No password is ever sent to any server, stored in any database, or logged anywhere. We literally have no way to see what passwords you generate. Close the tab and it's gone.
