Create Strong Password Online — Free Secure Password Generator

Why do you need a strong password?

According to statistics, 80% of data breaches involve weak or stolen passwords. A strong password is the first line of defense protecting your online accounts.

Metoolzy Password Generator creates truly random passwords using crypto.getRandomValues() — not Math.random().

Features

• Secure Cryptography — Uses Web Crypto API (crypto.getRandomValues) for true randomness
• Fully customizable — Length (4-64 characters), toggle: uppercase (A-Z), lowercase (a-z), numbers (0-9), symbols (!@#$…)
• Strength meter — Strength indicator bar: Weak → Fair → Strong → Very Strong
• 1-click copy — Copy the password to the clipboard instantly
• Client-side — Passwords are generated in the browser, not sent anywhere, and not saved

What makes a strong password?

• ✅ At least 12 characters (16+ is better)
• ✅ Uppercase + lowercase letters
• ✅ Numbers
• ✅ Special symbols (!@#$%^&*)
• ❌ Do not use dictionary words, birthdates, or names
• ❌ Do not reuse for multiple accounts

Time required to crack a password

Length	Lowercase only	+ Uppercase + numbers	+ Symbols
6 characters	1 second	10 minutes	2 hours
8 characters	10 minutes	2 days	2 months
12 characters	200 years	3,000 years	3 million years
16 characters	10 billion years	∞	∞

Source: brute-force estimates at 10 billion guesses/second

Frequently Asked Questions

Are passwords saved anywhere?

No. Passwords are generated entirely in the browser using the Web Crypto API. They are not sent to the server, nor saved in cookies or localStorage.

Is crypto.getRandomValues more secure than Math.random?

Yes. Math.random() is pseudo-random and predictable. crypto.getRandomValues() uses entropy from the operating system — making it unpredictable.

Should I use a password manager?

Yes. Create a strong password using Metoolzy, then save it to a password manager (like Bitwarden, 1Password, LastPass) so you don’t have to remember it.
