What is the Password Generator?

The Password Generator is a free, browser-based security tool that creates strong, random passwords using cryptographically secure randomness provided by the Web Cryptography API (window.crypto.getRandomValues). Unlike pseudo-random number generators, this method produces entropy that is suitable for security-sensitive applications such as account passwords, encryption keys, and API secrets. You can customise every aspect of the generated password — length, character sets, exclusion of visually similar characters, and whether characters can repeat.

Cybersecurity experts universally recommend using a different strong password for every account. Data breaches expose billions of credentials annually, and attackers use credential stuffing attacks to test stolen username/password pairs across hundreds of websites. A randomly generated 16-character password with mixed case, numbers, and symbols takes effectively infinite time to crack by brute force, providing robust protection for your accounts.

How to Use — Step-by-Step

  1. Set your desired password length using the slider (4–128 characters).
  2. Check or uncheck character type options: Uppercase (A–Z), Lowercase (a–z), Numbers (0–9), and Symbols.
  3. Optionally enable Exclude Similar to remove confusable characters like I, l, 1, O, and 0.
  4. Enable No Repeating Chars if you want every character to appear only once.
  5. Set the Quantity field to generate multiple passwords at once (up to 50).
  6. Click Generate Password and use the copy button to grab your new password.

Key Features & Benefits

🔐
Cryptographically Secure

Uses window.crypto.getRandomValues for true cryptographic entropy — the same standard used in security software.

📏
4–128 Character Length

Generate passwords from 4 characters (PIN-style) up to 128 characters for maximum security scenarios.

💪
Strength Meter

Visual strength indicator rates your password from Weak to Strong based on length, complexity, and character diversity.

📋
Bulk Generation

Generate up to 50 passwords simultaneously — useful for provisioning accounts, testing, or creating password lists.

🕒
Session History

Remembers the last 20 passwords generated during your session so you can refer back without regenerating.

🔒
100% Private

Generated passwords are never stored or transmitted. Everything runs entirely in your browser session.

Frequently Asked Questions

❓ Is the Password Generator free to use?
Yes, completely free with no usage limits, no account requirements, and no ads. Generate as many passwords as you need for any purpose at no cost.
❓ Is my data secure? Are passwords transmitted anywhere?
Generated passwords are never transmitted, logged, or stored in any database. All password generation happens exclusively in your browser using JavaScript's crypto API. The passwords exist only in your browser memory and disappear when you close the tab.
❓ How long should my password be?
Security experts recommend at least 12 characters for general accounts and 16 or more for sensitive accounts like banking, email, and cloud storage. For passwords protecting encryption keys or master password managers, 20+ characters provides an astronomical number of possible combinations that modern computers cannot brute-force.
❓ Should I include symbols in my password?
Including symbols significantly increases password entropy. A 12-character password using only lowercase letters has about 95 trillion possible combinations. Adding uppercase, numbers, and symbols expands the search space to over 475 quadrillion combinations — making brute-force attacks effectively impossible.
❓ What character sets are available?
You can mix and match four sets: uppercase letters (A–Z), lowercase letters (a–z), digits (0–9), and symbols (!@#$%^&*...). You can also define a custom symbol set and exclude visually similar characters like I, l, 1, O, and 0 to avoid transcription errors.
