How to Generate a Strong Password with Toolzey
Creating a strong password is one of the most important steps in protecting your online accounts. Here's how to use Toolzey to generate the perfect password:
- Choose a length — We recommend at least 16 characters for accounts you care about. Use the slider or type a number directly.
- Select character types — Including uppercase, lowercase, numbers and symbols makes passwords exponentially harder to crack.
- Exclude confusing characters — Optionally exclude characters like 0, O, l, 1 and I if you ever need to type the password manually.
- Click Generate — A cryptographically secure random password is created instantly using your browser's
crypto.getRandomValues()API. - Copy and save — Click the copy button or the password itself. Store it immediately in a password manager like 1Password, Bitwarden, or Dashlane.
Why Use Toolzey Password Generator?
Toolzey uses the Web Cryptography API (window.crypto.getRandomValues()) to generate passwords. This is the same cryptographic randomness used in SSL certificates and financial encryption — not a predictable Math.random(). Your generated passwords are:
- Never sent to any server — all generation happens in your browser
- Never logged or stored — closing the tab deletes all passwords
- Cryptographically secure — impossible to predict or reverse-engineer
- Truly random — not based on any seed, pattern or time
Frequently Asked Questions
Yes. Toolzey uses the browser's
window.crypto.getRandomValues() API, which provides cryptographic-quality randomness. This is far more secure than Math.random() and is the same method used in cryptographic software.Absolutely not. All password generation happens entirely in your browser. No passwords are sent to any server, logged, or stored in any database. When you close the tab, all history is gone.
A strong password is: at least 12 characters long (16+ is better), includes uppercase and lowercase letters, numbers, and symbols, is not based on dictionary words or personal information, and is unique to each account.
A 16-character password with all character types has approximately 7 × 10²⁸ possible combinations. Even at 1 trillion guesses per second, it would take longer than the age of the universe to crack.
Never write passwords on paper or in an unencrypted file. Use a reputable password manager such as Bitwarden (free, open-source), 1Password, Dashlane, or your browser's built-in password manager.
