About Random Password Generator

About This Tool

Random Password Generator is a free, open-source tool designed to help you create strong, secure passwords for all your online accounts. With multiple generation methods and advanced security features, you can generate passwords that are both secure and memorable.

Our tool offers several types of password generators:

  • Random Character Generator - Creates passwords using a mix of letters, numbers, and special characters
  • Memorable Password Generator - Uses random words to create passwords that are easier to remember
  • Pronounceable Generator - Creates passwords using syllable patterns for easier typing
  • Specialized Generators - Generate PINs, API keys, and cryptographic salts
  • Bulk Generator - Create multiple passwords at once with export options

Security & Privacy

100% Client-Side Generation

All passwords are generated entirely in your browser using JavaScript. Nothing is ever sent to our servers. Your passwords never leave your device.

Cryptographically Secure Random Numbers

We use the browser's built-in crypto.getRandomValues() API, which provides cryptographically strong random numbers suitable for password generation. This is far superior to JavaScript's Math.random() function.

No Logging or Tracking

We don't log, store, or track any passwords you generate. We don't use analytics that track your behavior. Your privacy is our priority.

Open Source

Our code is transparent and can be audited. You can view the source code to verify that no passwords are being transmitted or stored.

Breach Checking

Our breach checker uses the Have I Been Pwned API with k-anonymity. Only the first 5 characters of your password's SHA-1 hash are sent to the API, ensuring your actual password is never transmitted.

Frequently Asked Questions

We recommend at least 12-16 characters for random passwords. The longer your password, the more secure it is. For memorable passwords, 4-5 words provide excellent security while remaining easy to remember.

Yes! Including special characters (!@#$%^&*) significantly increases password strength. However, length is even more important than complexity. A 16-character password with only letters is stronger than an 8-character password with all character types.

Entropy measures password unpredictability in bits. Higher entropy means more possible combinations an attacker must try. We recommend passwords with at least 60 bits of entropy. Our strength meter shows the entropy for each generated password.

This depends on your use case. Ambiguous characters like 0/O, 1/l/I, and 5/S can be confusing when typing or reading passwords. If you need to manually type your password frequently, excluding these characters can reduce errors. However, if you're using a password manager (which we recommend), ambiguous characters are fine.

Memorable passwords use the "diceware" method - combining random words from a list. For example: "Correct-Horse-Battery-Staple". While easier to remember than random characters, they're still highly secure due to the large number of possible word combinations. A 4-word password from our 1000-word list has about 40 bits of entropy.

Yes, absolutely! Password managers are the best way to handle passwords. They can generate, store, and auto-fill strong unique passwords for every site. Popular options include 1Password, Bitwarden, LastPass, and Dashlane. Use our generator to create a strong master password for your password manager.

The breach checker uses the Have I Been Pwned API with k-anonymity protection. Your password is hashed using SHA-1, and only the first 5 characters of the hash are sent to the API. The API returns all breached passwords matching that prefix, and your browser checks locally if your password is in that list. This means your actual password is never transmitted.

Yes! Once the page is loaded, all password generation happens client-side in your browser. You can even save the page and use it offline. Note that the breach checker and Google Sheets export require an internet connection.

The QR code feature lets you easily transfer a password from your computer to your mobile device. Simply scan the QR code with your phone's camera or a QR scanner app. This is useful when setting up accounts on mobile devices or sharing Wi-Fi passwords.

Yes! This tool is completely free to use with no limitations. There are no premium features, no ads, and no hidden costs. We created this tool to help people stay secure online.

Password Best Practices

  • Use unique passwords for every account. If one site is breached, attackers can't access your other accounts.
  • Make passwords long - at least 12-16 characters for important accounts.
  • Enable two-factor authentication (2FA) wherever possible for an extra layer of security.
  • Never reuse passwords across multiple sites.
  • Don't share passwords via email, text, or insecure messaging apps.
  • Change passwords if you suspect an account has been compromised.
  • Use a password manager to securely store all your passwords.
  • Avoid personal information like birthdays, names, or addresses in passwords.
  • Regular updates aren't necessary unless there's a breach. Frequent changes can lead to weaker passwords.
