Free Password Generator

Generate strong, random, cryptographically secure passwords. Adjust the length, pick which character classes to include, exclude look-alike characters, and copy with one click. Runs entirely in your browser — passwords are never sent to a server.

Character types

Generated in your browser. We use crypto.getRandomValues() — the same cryptographically-secure RNG SSH and TLS use. No password is ever sent to our servers.

Strength

Very strong

103 bits of entropy from a 88-character pool

Why use this generator

  • Setting up a new account and need a unique password that isn't reused from another site.
  • Rotating credentials after a vendor breach — you want 20+ characters of true randomness, not a clever pattern you'll forget.
  • Generating an admin password for a server, router, or database where you'll paste it into a vault and never type it again.
  • Creating a WiFi guest password to print on the menu QR card — short enough to type, long enough to be safe.
  • Bulk-generating 10 distinct passwords for a fresh device fleet or test environment.

How it works

  1. 1Slide the length to match the policy you need — 8 for legacy systems, 16 for modern web accounts, 32+ for crypto keys and admin credentials.
  2. 2Pick which character classes to include. Uppercase + lowercase + numbers + symbols is the strongest default; drop a class if the target system rejects it.
  3. 3Optionally exclude look-alike characters (0/O, l/1/I) — useful when the password will be read off a screen or written down.
  4. 4Click Generate (or change any control — passwords regenerate live). The strength bar shows entropy in bits; aim for ≥ 80 for anything important.
  5. 5Click Copy. The password lives in your clipboard for ~30 seconds before most systems auto-clear; paste it into your password manager immediately.

Frequently asked questions

Are the passwords really random?
Yes. We use crypto.getRandomValues() — the Web Crypto API's cryptographically-secure random number generator. It's seeded by your operating system's entropy pool, the same source used by SSH, TLS, and your OS's full-disk encryption. We do NOT use Math.random(), which is predictable and unsuitable for security purposes.
Do you store or log generated passwords?
No. Every password is generated in your browser via JavaScript that runs locally. Nothing is sent to our server, our analytics, or anywhere else. Close the tab and the password is gone — copy it before you close.
How long should my password be?
16 characters with mixed classes (~95 bits of entropy) is strong for any consumer account. 20–24 for financial accounts. 32+ for crypto wallet seeds, server root accounts, and master passwords on your password manager. Length matters more than complexity — a 20-character all-lowercase password beats a 10-character symbol-soup password.
What's entropy and why should I care?
Entropy in bits measures how many guesses an attacker needs to try every possible password of that shape. 40 bits = a few hours on a laptop. 60 bits = months on a GPU rig. 80 bits = lifetime of the universe on current hardware. Our strength bar maps to these thresholds: weak < 40, fair 40–59, strong 60–79, very strong ≥ 80.
Should I exclude ambiguous characters?
Only if you'll be typing the password by hand from a printed copy or reading it off a screen to someone else. The exclusion drops 0/O, l/1/I, and the pipe character — slightly shrinking the pool but eliminating the most common transcription errors. For passwords going straight into a password manager, leave the option off and keep the full entropy.
Should I use a password manager?
Yes — that's the entire point of strong random passwords. Generate it here, paste it into 1Password, Bitwarden, KeePassXC, or your browser's built-in manager, and never see it again. Trying to remember 16-character random strings is the failure mode; the password manager is the solution.
Why are some character classes off by default at some sites?
Many legacy systems reject symbols (or specific symbols like #, %, or backtick) because of SQL-injection paranoia from the early 2000s. Modern systems should accept any character — but if your password keeps getting rejected, turn off the symbols toggle and bump the length up by 4 characters to keep the entropy the same.
Securing your business beyond passwords?
Strong passwords are step one. You'll also want a Privacy Policy and Terms of Service for any website that takes user data. Generate both free at /privacy-policy-generator and /terms-of-service-generator — same browser-only approach, no signup.
