Password Generator

Create a long, random password locally with cryptographically secure browser randomness.

Generated password

Ready to copy

Pool-based estimate

estimated bits based on length and character pool. This is a guide, not a cracking-time guarantee.

Customize

Each enabled character group will appear at least once.

Include characters

Private by design

Generated only on your device

The password never leaves this page. Generation uses crypto.getRandomValues(), not Math.random(), and rejects biased random values before selecting characters.

Safer accounts

Long, random, and unique

Use a different password for every account and save it in a reputable password manager. Turn on multifactor authentication wherever it is available.

Good practice

Use generated passwords safely

Prefer lengthThe 20-character default provides a large search space while remaining compatible with most services.
Never reuseA unique password limits the damage if another website suffers a data breach.
Store it securelyMove the result directly into a password manager instead of saving it in notes or email.

Learn more from NIST’s current authentication guidance, CISA’s password-manager guidance, and the Web Cryptography specification.

How to use it

Get a reliable result

  1. Choose a password length and the character groups to include.
  2. Optionally exclude ambiguous characters, then generate a new value.
  3. Copy the password into a trusted password manager and clear the page when finished.

Useful for

Common workflows

  • Create a unique password for a new account
  • Generate a long credential for a device or service
  • Avoid predictable personal words and manual patterns

Examples

What to expect

Long mixed password
Input
24 characters using upper, lower, numbers, and symbols
Output
A cryptographically random value containing every selected group

Know before you start

Important limitations

  • A strong generated password cannot protect a compromised device, phishing victim, or insecure service.
  • Some sites restrict symbols or maximum length, so their published password rules still apply.
  • Clipboard contents may be readable by other software on the device until replaced or cleared.

Common questions

Password Generator FAQ

What makes the result random?

The generator uses the browser's cryptographic random-number API and rejection sampling rather than Math.random.

Does Tool Packer save generated passwords?

No. Generation and copying happen in the current browser and no password is sent to Tool Packer.

Should I reuse a generated password?

No. Use a separate password for each account and store it in a reputable password manager.

Browser-local

Processed on your device

Generation happens entirely in this browser. Tool Packer does not receive or store your password.

How this processing works

The tool reads and processes this input in your browser. Tool Packer's application server does not receive the input or generated result.
