Free Password & Passphrase Generator
By Jaden Vo · Free · Private (browser-only)
Create a strong random password or a memorable multi-word passphrase without sending anything to a server. Use the generator when you need a one-off secret, then store it in a password manager — or skip typing entirely and turn on a passkey where the site supports one.
Generated with crypto.getRandomValues in your browser. Nothing is uploaded or stored on our servers.

Rough entropy estimate: ~123 bits (teaching figure from pool size × length — not a lab audit).
Why generate passwords in the browser?
People still invent passwords from names, sports teams, and keyboard walks because those strings are easy to remember. Attackers know that. A generator removes the creative burden: it samples from a defined character pool (or word list) using the browser’s cryptographic random source. This page never needs your email, never opens a network request for the secret, and never stores what you copy. That privacy model matches our password strength checker — check a candidate there after you generate one here if you want a second opinion on length and variety.
Browser-side generation is still not magic. If malware can read your clipboard or a phishing page tricks you into typing the new password on the wrong domain, randomness will not save you. Unique passwords per site, a manager, multi-factor authentication, and passkeys close those gaps better than any single “strong looking” string.
Random passwords vs passphrases
A random password mixes letters, digits, and symbols to a length you choose (default 20 here). Managers love these: they autofill, so you rarely type them. Ambiguous characters (like 0/O) are removed from our pools to reduce copy errors when you must type by hand.
A passphrase strings several unrelated dictionary words (optionally capitalized, with a separator and a trailing number). Passphrases shine when you must enter a secret on a TV, a friend’s laptop, or a BIOS prompt. Entropy comes from how many words you pick and how large the word list is — not from leetspeak tricks. Four short related words are weaker than five or six unrelated ones.
Neither format beats a passkey on phishing resistance. Passkeys are bound to the real website, so a look-alike login page cannot silently accept them the way a typed password can. Read passkeys vs passwords and how passkeys work when you are ready to upgrade Google, Apple, and banking accounts.
How to use this tool safely
- Generate a password or passphrase with the controls above.
- Copy it once, paste it into your password manager or the signup form, then clear the clipboard if you share the device.
- Do not reuse the same secret on a second site. Generate again.
- Turn on an authenticator app (not only SMS) for email and finance — see SMS 2FA vs authenticator apps.
- Where passkeys are offered, add one and keep a recovery path documented.
For day-to-day life, prefer generating inside a manager such as NordPass (affiliate link) so the secret never lingers in a browser tab. Our guide Is a password manager safe? NordPass vs browser passwords covers zero-knowledge claims, free vs paid tiers, and when the built-in browser manager is “good enough.”
What this tool does not claim
- It does not check whether a password already appeared in a breach (that would require sending the secret or a hash to a third party).
- The bit estimate is educational math from pool size, not a penetration-test result.
- It does not replace device updates, phishing caution, or HTTPS hygiene on public Wi-Fi — see our public Wi-Fi safety quiz.

FAQ
Is the generated password sent to your servers?
No. Generation uses the Web Crypto API (crypto.getRandomValues) entirely in your browser. We do not upload, log, or store what appears in the box.
Password or passphrase — which should I use?
Both can be strong. A long random password (16–20+ mixed characters) is hard to guess and easy for a manager to fill. A 5–6 word passphrase is easier to type when you must enter it by hand (disk unlock, some shared devices). Prefer a password manager so you rarely type either from memory.
How long should a password be?
Length is the biggest lever. Twelve characters with mixed types is a common minimum; 16–20+ is better for high-value accounts. CISA’s Secure Our World guidance emphasizes long, unique passwords — ideally stored in a manager — and turning on multi-factor authentication.
What does the “bits” estimate mean?
It is a rough teaching number from character-pool (or word-list) size times length. It is not a laboratory audit, not a guarantee against phishing, and not a substitute for unique passwords per site.
Should I still use a password manager?
Yes for most people. Managers generate and store unique secrets so you are not copying from a web page into every signup. See our NordPass vs browser passwords guide. Where sites offer passkeys, those resist phishing better than typed passwords.
Can I use this generator offline?
If the page is already loaded (or installed as a cached static page), the script runs locally. For day-to-day use, generate inside your password manager so the secret never sits in a browser tab.
