How secure is this password generator?

Every password is built on your own device with the browser's Web Crypto API (crypto.getRandomValues), a cryptographically secure random source — not the predictable Math.random that many websites use. Nothing is sent to our servers, so we never see or store a password you generate.

What makes a strong password?

Length first: aim for at least 16 characters. Mix uppercase and lowercase letters, numbers, and symbols, and make sure the password is genuinely random rather than built from names, dates, or keyboard patterns. The strength meter on this page rates each result from Weak to Very Strong as you adjust the settings.

Do you store or send my generated password anywhere?

No. The generator runs entirely in JavaScript inside your browser, so passwords are never uploaded, logged, or saved on our servers. The handful of results listed under Recent Passwords exist only in the page and disappear the moment you close or reload the tab.

How long should my password be?

Sixteen characters is a sensible default for everyday accounts, which is where the slider starts. Use 20 or more for email, banking, and the master password of a password manager, since those protect everything else. The slider goes up to 128 characters for sites that allow it.

Should I reuse passwords or use a password manager?

Never reuse a password — one breached site then exposes every account that shares it. Generate a unique password for each account and store them in a password manager, so the only thing you have to remember is one strong master password.

Password Generator — Strong Random Passwords

Free online password generator — create a strong random password

Weak and reused passwords are still the easiest way into an account. This free password generator builds a strong, genuinely random password inside your browser in one click. Set the length, pick the character types, and copy the result — no sign-up and no limits.

How to generate a strong password

Drag the Password Length slider — anywhere from 4 to 128 characters.
Tick the character types to include: Uppercase (A–Z), Lowercase (a–z), Numbers (0–9), and Symbols (!@#…).
Turn on Exclude ambiguous characters if it will be typed by hand, so 0 and O, or l and 1, cannot be confused.
Click Generate, press Show to reveal it, then Copy Password. Regenerate gives you another instantly.

What makes a password strong

Length matters most — every extra character multiplies the combinations an attacker must work through. Mixing uppercase, lowercase, numbers, and symbols widens the character pool, and true randomness removes the patterns cracking tools try first: names, birthdays, keyboard runs, and old favourites like Password1!. The strength meter under the output rates each result from Weak to Very Strong.

When to use a generated password

Signing up, or replacing a password you reused elsewhere.
Setting database, server, Wi-Fi, or admin panel credentials.
Creating API keys, seeds, and one-off tokens.
Rotating a password after a breach notification.

Your password never leaves your browser

Every password is created on your own device with the Web Crypto API (crypto.getRandomValues) — the cryptographically secure random source browsers use to build encryption keys, not the predictable Math.random. Nothing is sent to our servers, logged, or saved, and the Recent Passwords shortlist lives only in the page until you close the tab.

Handing the password to a teammate or client? Do not paste it into email or chat, where it lingers in inboxes and message history. Send it with our One-Time Secret tool — an encrypted link destroyed after one view.
