All passwords are generated locally in your browser using the cryptographically secure crypto.getRandomValues() API. Nothing is sent to any server. We never see, store, or log your passwords.

Password Generator

Generate strong, secure passwords instantly in your browser. Our password generator uses the cryptographically secure crypto.getRandomValues() API to produce truly random passwords that are impossible to predict. Choose from three modes — Random passwords, Passphrases (word-based), and PINs — to match any security requirement.

Unlike many online password generators that send data to their servers, our tool runs 100% locally in your browser. Your passwords are never transmitted, stored, or logged anywhere. With bulk generation, estimated crack time display, and a clean ad-free interface, this is the most developer-friendly password generator on the web.

Whether you need a single strong password for a new account, a memorable passphrase for your master password, or multiple passwords for a batch of test accounts, this tool has you covered with full customization and real-time strength analysis.

Key Capabilities

  • Three generation modes: Random passwords (4-128 characters), memorable passphrases (3-10 words), and numeric PINs (4-12 digits) cover every use case.
  • Full customization: Toggle uppercase, lowercase, numbers, and symbols. Exclude ambiguous characters (0/O, 1/l/I) to avoid confusion when reading passwords.
  • Strength analysis: Real-time entropy calculation with a 5-level strength meter and estimated crack time so you know exactly how secure your password is.
  • Bulk generation: Generate up to 10 passwords at once — perfect for setting up test accounts, provisioning users, or comparing options.
  • Passphrase options: Customize word count, separator character, capitalization, and number inclusion to create memorable yet secure passphrases.
  • Cryptographically secure: Uses the Web Crypto API (crypto.getRandomValues()) for true randomness, the same standard used by password managers and security tools.

Privacy & Security

Every password is generated entirely in your browser. We use the Web Crypto API, the same cryptographic random number generator used by password managers like Bitwarden and 1Password. No passwords are ever sent over the network, stored on any server, or logged in any analytics system.

This approach is fundamentally more secure than server-side generators because your passwords never exist outside your own device. When you close the tab, the generated passwords are gone from memory. There is no server-side component, no database, and no way for anyone — including us — to see what you generated.

How to Use

  1. Choose your mode: Random for maximum security, Passphrase for memorability, or PIN for numeric codes.
  2. Adjust the length/word count and character options to match your requirements.
  3. Click Generate or adjust any option to instantly create new passwords.
  4. Click the copy icon next to any password to copy it to your clipboard.
  5. Use the Generate Count slider to create multiple passwords at once.
