Password Generator - Free Online Tool

Generate strong, random passwords in your browser with no signup and no data sent to any server. Choose a length between 8 and 32 characters and tick which character types to include: uppercase letters, lowercase letters, numbers, and symbols. The tool uses the Web Crypto API (crypto.getRandomValues) so each password is cryptographically random and suitable for account creation, API keys, or temporary access. All processing happens locally; nothing is stored or transmitted.

How to Use This Tool

  1. Set the password length (8 to 32 characters) using the number input.

Benefits of Using This Tool

  • Cryptographically secure randomness via the browser’s Web Crypto API.
  • No account or signup required; works entirely in your browser.
  • Configurable length and character sets to meet site or policy requirements.
  • Useful for one-off account signups, dev credentials, or temporary access.

When to Use Password Generator

  • Creating new account passwords when a site requires strong passwords.
  • Generating temporary or one-time passwords for sharing securely.
  • Producing dev or test credentials that meet complexity rules.
  • Quickly getting a random string for API keys or secrets in non-production environments.

Decision Guide

Best for

  • Users who need a strong password without reusing an existing one.
  • Developers and testers who need quick, compliant passwords for staging or demos.
  • Anyone who prefers not to install a separate password-manager app for a single password.

Avoid when

  • You need to store or sync passwords across devices (use a dedicated password manager instead).
  • Your organisation requires passwords from a specific approved generator or policy tool.

Example

Example generated password

Input

Length: 16, all character types enabled

Output

K9#mP2@xLq$vN7wR

Output changes every time you click Generate. Always use a unique password per account.

Troubleshooting

The tool says "Select at least one character type."

Enable at least one checkbox: uppercase, lowercase, numbers, or symbols.

My site rejects the password.

Some sites require a minimum length or specific character types. Match the length and options to the site’s rules (e.g. enable symbols if required).

FAQs

Is the password sent to a server?

No. Generation runs entirely in your browser using the Web Crypto API. Nothing is sent to or stored on any server.

How random are the passwords?

The tool uses crypto.getRandomValues, which is designed for cryptographically strong random values. It is suitable for generating passwords and similar secrets.

Can I use these for important accounts?

Yes, as long as you store the password securely (e.g. in a password manager) and use it only for that account. Do not reuse the same password across multiple services.
