Password Generator

Generate strong, random passwords with configurable length and character sets. Includes a password strength meter.

What is a Password Generator?

A password generator creates random, cryptographically secure passwords that are virtually impossible to guess or crack through brute force. In an era of frequent data breaches and credential stuffing attacks, using unique, strong passwords for every account is your first line of defense.

Our generator uses your browser’s built-in cryptographic random number generator (crypto.getRandomValues) to produce truly random passwords. No passwords are transmitted, stored, or logged — everything happens locally on your device.

How to Use This Password Generator

  1. Set the password length using the slider (16+ characters recommended)
  2. Select character types — uppercase, lowercase, digits, and/or symbols
  3. Click “Generate” to create a random password
  4. Check the strength meter to ensure sufficient complexity
  5. Copy the password and store it in your password manager

Common Use Cases

  • Account registration — Generate a unique password for each new online account
  • Database credentials — Create strong passwords for database users and service accounts
  • API keys and secrets — Generate random strings for environment variables and configuration
  • Wi-Fi passwords — Create memorable but strong passwords for network access
  • Temporary access — Generate one-time passwords for temporary shared access

Frequently Asked Questions

How long should my password be?

At least 16 characters for important accounts. Each additional character exponentially increases the time needed to brute-force the password. A 20-character password with mixed character types would take billions of years to crack with current technology.

Should I use special characters in passwords?

Yes, when possible. Special characters dramatically increase the character set (from 62 to 95+ possible characters per position), making passwords exponentially harder to crack. Some systems restrict certain special characters — adjust accordingly.

Is this password generator truly random?

Yes. It uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same randomness source used for TLS encryption in your browser.
