About This Tool

Password Generator

Generate strong, random passwords with custom length and character sets — and check password strength instantly.

Why Use This Tool?

  • Create strong, unique passwords for every online account
  • Generate passwords that meet specific requirements (uppercase, numbers, symbols)
  • Replace weak or reused passwords with cryptographically random ones
  • Generate bulk passwords for setting up multiple user accounts
  • Check the strength of your existing password before using it

Overview

Password security is the foundation of your digital safety. Despite years of warnings, weak and reused passwords remain the leading cause of account breaches. The most secure passwords are long, random, unique to each account, and include a mix of uppercase letters, lowercase letters, numbers, and special symbols. Our Password Generator creates cryptographically random passwords using your browser's built-in crypto.getRandomValues() function — the same randomness source used by banking applications and security software. You control the length (8–64 characters), character sets, and can exclude ambiguous characters like O/0 and I/l that can be visually confused. The built-in strength meter evaluates your generated password against entropy-based scoring criteria. Use it to generate strong master passwords for your password manager, secure API keys, temporary access tokens, or any scenario where a robust random password is needed.

How to Use

  • 1

    Set Password Length

    Use the slider to choose your desired password length. 16 characters is a good minimum for most accounts; 24+ for high-security accounts.

  • 2

    Choose Character Types

    Enable Uppercase (A-Z), Lowercase (a-z), Numbers (0-9), and Symbols (!@#$%) as needed. More types = stronger password.

  • 3

    Optional: Exclude Ambiguous Characters

    Enable "Exclude Ambiguous" to remove characters like O, 0, l, I, and 1 that can be confused visually when reading or copying.

    Click Copy to clipboard. Save it immediately in your password manager (Bitwarden, 1Password, or KeePass recommended).

Frequently Asked Questions

Yes. Passwords are generated using window.crypto.getRandomValues(), the browser's cryptographically secure pseudorandom number generator (CSPRNG). No server is involved.
Minimum 12 characters for general accounts. 16+ for important accounts. 24+ for master passwords. Every additional character exponentially increases the time to crack.
Absolutely. A password manager (Bitwarden, 1Password, Dashlane) lets you use unique, complex passwords for every account without memorising them. Use this generator with your password manager.
Length is the most important factor. A 20-character lowercase-only password is stronger than a 10-character password with symbols. Aim for length + mixed character types.
Yes. For WiFi, WPA2/WPA3 allows passwords up to 63 characters. A 20+ character random password is extremely difficult to crack even with modern hardware.
