Question 1

How does QTool.io's password generator work?

Accepted Answer

QTool.io's password generator uses your browser's built-in Web Crypto API (crypto.getRandomValues) to generate truly random, cryptographically secure passwords. Everything runs client-side — no passwords are ever sent to any server.

Question 2

What makes a password strong?

Accepted Answer

A strong password is long (16+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, and is randomly generated rather than human-chosen. QTool.io shows entropy bits and estimated crack time so you can gauge strength instantly.

Question 3

Is it safe to generate passwords online?

Accepted Answer

Yes, when the tool runs entirely in your browser like QTool.io's generator does. No data leaves your device. The passwords are generated using the Web Crypto API and are never transmitted or stored anywhere.

Question 4

What is a passphrase and why use one?

Accepted Answer

A passphrase is a password made of random words, like 'correct-horse-battery-staple'. Passphrases are easier to remember than random character passwords while being extremely secure. A 5-word passphrase from QTool.io's 1296-word list has over 54 bits of entropy.

Question 5

Can I generate multiple passwords at once?

Accepted Answer

Yes, QTool.io lets you generate up to 10 passwords or passphrases at once. Customize length from 8 to 128 characters, choose character sets, exclude specific characters, and copy any password with one click. You can also copy all generated passwords at once.
