Generate secure passwords, passphrases, PINs in bulk with strength analysis.

No weak patterns detected!
Create genuinely strong passwords in seconds — the kind hackers hate. This generator uses your browser's cryptographic random engine (the same technology behind HTTPS security), not basic Math.random like most online generators. Choose from seven modes: a full custom generator with presets and character options, speakable passwords you can read aloud over the phone, memorable combos like Blue$Tiger392, XKCD-style passphrases like correct-horse-battery-staple, secure PINs, and bulk generation of up to 50 passwords at once.
Every password gets a live strength meter with entropy in bits and estimated crack time, plus automatic pattern warnings that catch weak spots like sequences and common words. Includes an exclude-confusing-characters option for passwords you'll actually type correctly, and a session history of your last 10 generations. Everything happens locally in your browser — nothing is ever sent to a server.
Yes — it uses your browser's built-in cryptographic random generator (crypto.getRandomValues), the strongest source of randomness available in a browser. Everything runs locally, so no password ever leaves your device or touches a server.
Length first, then variety. A 16-character password mixing uppercase, lowercase, numbers and symbols is dramatically harder to crack than an 8-character one. The strength meter shows your entropy in bits and estimated crack time so you can see the difference live.
A passphrase is a sequence of random words joined together, like correct-horse-battery-staple. It's long (which means strong) but easy to remember and type — ideal for your main email or password manager master password.
Some characters look identical in many fonts — 0 versus O, or 1 versus l and I. If you'll ever need to type your password by hand (on a TV, a game console, or a phone), excluding them prevents frustrating failed logins.
The tool automatically detects weak patterns: repeated characters, sequences like 123 or abc, famous weak passwords like password and qwerty, and too-short lengths. Passwords with these patterns get cracked first, so regenerate if a warning appears.
6 digits minimum for anything that matters. 4-digit PINs only have 10,000 combinations, which is why the tool warns you when generating shorter ones. Use 4 digits only for low-risk things like a bike lock.
No. Passwords live in your browser's memory only — the History tab keeps your last 10 for the current session and disappears when you close the tab. Nothing is transmitted or saved anywhere.
Yes — Bulk mode creates up to 50 passwords at your chosen length, each with its own copy button plus a Copy All option. Perfect for setting up teams, classrooms, or new accounts.
