Password Generator: Complete Usage Guide

Purpose

The Password Generator produces random strings using your browser's cryptographic random source, not the weak pseudo-random function many web tools still rely on. Humans are predictable: we reach for keyboard patterns, birth years, pet names and substitutions like 'a' to '@', all of which sit in every cracking dictionary. A generated 16- to 20-character password removes that problem entirely. Nothing is transmitted, logged or stored — the password exists only in your browser until you copy it.

How to use it

1. 1Set the length. 16 characters is a sensible default; use 20 or more for email, banking and cloud infrastructure.
2. 2Toggle the character classes you need: uppercase, lowercase, numbers and symbols. Keep all four unless the site forbids symbols.
3. 3Click Generate — or regenerate until you get one you are happy with.
4. 4Copy the password and paste it straight into your password manager, not into a note or a chat window.

Tips & tricks

• Length beats complexity. Entropy grows exponentially with length and only linearly with the character set.
• Use a unique password for every account. Reuse is what turns one breach into ten compromised accounts.
• Generate your email password first and make it the longest — email is the reset key to everything else.
• Exclude ambiguous characters if you will ever type the password manually on a TV or console.
• Turn on two-factor authentication as well; a strong password still cannot survive a phishing page.
