About this Password Generator

The Password Generator is a free online security tool that creates strong, cryptographically random passwords with customizable length and character sets. In an era of frequent data breaches and account hacks, using strong unique passwords is essential for online security. This secure password generator creates passwords using your browser's cryptographic random number generator, supporting lengths from 4 to 128 characters with options for alphanumeric, letters-only, or numeric PIN-style passwords.

How to use the Password Generator

  1. 1 Set the desired password length in the "Password Length" field (4 to 128 characters, default 16).
  2. 2 Select the character set from the "Include" dropdown: All characters (with symbols), Letters + Numbers, Letters only, or Numbers only (PIN).
  3. 3 Click the Run button to generate a cryptographically secure random password.
  4. 4 Copy the generated password and use it immediately. The password is generated locally and never transmitted.

Frequently Asked Questions

How secure are the generated passwords?
This tool uses the Web Crypto API's crypto.getRandomValues() method, which is cryptographically strong and suitable for security-sensitive applications. A 16-character password with all character types has approximately 10^30 possible combinations, making it infeasible to brute-force.
What is the recommended password length?
For most purposes, a 16-character password provides excellent security. For high-security accounts like email and banking, use 20-30 characters. The tool supports up to 128 characters for maximum security needs.
Are the passwords stored or transmitted anywhere?
No, passwords are generated entirely in your browser using client-side JavaScript. They are never sent to any server, stored in any database, or logged. This ensures your generated passwords remain completely private.
Can I generate a numeric PIN code?
Yes, select "Numbers only (PIN)" from the Include dropdown to generate a numeric-only password. This is useful for PIN codes, numeric passcodes, or systems that only accept digits. The minimum length is 4 characters.
