Password Generator

Password Generator builds strong, random passwords entirely inside your browser tab, so the string you copy never travels over the network. It draws each character from crypto.getRandomValues, the Web Crypto API's cryptographically secure random source, instead of Math.random() — which is fast but predictable and unsafe for anything you need to keep secret. You decide the exact makeup: drag the length control anywhere from 8 to 64 characters, then switch on the character classes you want — lowercase (a–z), uppercase (A–Z), digits (0–9), and symbols such as !@#$%^&*. Two convenience toggles handle real-world friction: "exclude similar characters" drops ambiguous glyphs like 0/O and 1/l/I so a password is safe to read off a screen and type by hand, and turning symbols off produces a password that still passes on sites which reject punctuation. The math is what makes this worthwhile. People invent passwords around names, birthdays, and keyboard runs like "qwerty," patterns that offline cracking rigs test in seconds. A truly random 16-character password using all four classes sits near 95^16 combinations — roughly 10^31 — which puts brute force out of reach. Because generation is instant and local, you can tap Generate repeatedly with no cost and no exposure until you get a string you like. Typical jobs: minting a unique login for every new account so one breach can't unlock the others, replacing a password right after a leak, creating a Wi-Fi passphrase, or seeding a service-account or API credential. The tool is meant to sit next to a password manager: generate here, copy, paste into your vault, and let the manager remember it so you never reuse a password twice. Developers, IT admins, and freelancers juggling dozens of client logins get the most out of it, but anyone tired of inventing passwords benefits. Two habits matter more than any setting: favor length over exotic complexity, and never build a password from personal information. Everything runs client-side, so once the page has loaded you can even go offline and the generator keeps working.
