Password generator

Create cryptographically random passwords with adjustable length and character sets. Nothing is sent to a server.

Estimated entropy: ~0 bits (length × log₂ of character pool).

What makes a password strong?

  • Length: longer passwords exponentially increase the work needed to guess them.
  • Variety: mixing uppercase, lowercase, digits, and symbols enlarges the search space.
  • Randomness: truly random strings resist dictionary and pattern-based attacks better than memorable phrases unless you use a vetted passphrase method.
  • Uniqueness: use a different strong password (or a password manager) for each account so one breach does not compromise the rest.

How it works

  1. Choose how long the password should be and which character sets to include.
  2. The tool uses your browser's crypto.getRandomValues() API so each character is drawn from a uniform random distribution (no Math.random()).
  3. At least one character from each selected set is included, then the result is shuffled.
  4. Copy the password and store it in a password manager; this page does not log or transmit it.

FAQ

Is it safe to generate passwords in the browser?

This tool runs entirely on your device. Random bytes come from the browser's cryptographic API, and the password is not uploaded to ToolPilot servers. For maximum assurance, use a reputable password manager with its own generator and keep your devices updated.

Why avoid predictable passwords and dictionary words?

Attackers try common passwords, leaked lists, and dictionary words first. Random passwords are not guessable by those shortcuts, so they hold up better against automated cracking when a hash leaks.

How long should my password be?

For general web accounts, aim for at least 12–16 random characters with mixed character types. Higher-value accounts (email, banking, crypto) deserve longer secrets or hardware-backed factors. A password manager makes long random passwords practical.

Should I reuse passwords across sites?

No. When one service is breached, reused passwords let attackers try the same login elsewhere. Unique passwords contain the blast radius; pairing them with two-factor authentication adds another layer when available.
