Is this password generator safe to use?

Yes. ToolKnit's password generator runs entirely in your browser. No passwords are sent to any server, stored, or logged. The randomness comes from the Web Crypto API (crypto.getRandomValues), which is cryptographically secure.

How long should a strong password be?

A strong password should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. 16 characters or more is recommended for important accounts.

What makes a password strong?

A strong password is long (12+ characters), random (not based on dictionary words or personal info), and uses a mix of character types (uppercase, lowercase, digits, symbols). Avoid patterns like '123456', 'password', or keyboard walks like 'qwerty'.

Can I generate multiple passwords at once?

Yes. ToolKnit's password generator lets you generate up to 50 passwords at once with the bulk generation feature. All passwords use the same settings you configure.

Does this tool store my passwords?

No. Passwords are generated in your browser and never sent anywhere. When you close or refresh the page, all generated passwords are gone. We recommend copying your password to a password manager immediately.

Strength Analysis

Real-time entropy calculation and estimated crack time so you know exactly how strong your password is.

Password Best Practices

• Use 16+ characters — Longer passwords are exponentially harder to crack.
• Mix all character types — Uppercase, lowercase, numbers, and symbols together.
• Never reuse passwords — Use a unique password for every account.
• Use a password manager — Don't try to memorize random passwords. Let a manager handle it.
• Enable 2FA — A strong password + two-factor authentication = maximum security.
