What is a password generator?

A password generator creates long, truly random passwords that humans could never guess or remember unaided — exactly why they work. This free generator runs offline in your browser using cryptographic randomness, lets you choose length (8–64) and character types, and shows a live strength meter. No signup, nothing stored, nothing sent.

How to use this password generator

  • Step 1: Set the length — 16 characters is a strong default, 20+ is even better.
  • Step 2: Tick the character types you want. All four is best; if a site bans symbols, untick Symbols and add length instead.
  • Step 3: Tap Generate, check the strength meter, then Copy.
  • Step 4: Paste it into the site and save it in a password manager. Generate a different one for every account.

What makes a password strong?

Length beats cleverness. Every extra character multiplies the guesses an attacker needs. A 16-character random password from the full character pool has over 100 bits of entropy — billions of years to brute-force with current technology. A short, “clever” password like a pet's name plus a year falls in seconds, because attackers try names, dates and common patterns first.

Password rules that actually work in 2026

  • Unique password for every account — no exceptions.
  • At least 16 characters, randomly generated.
  • Store them in a password manager so you only memorise one master password.
  • Turn on two-factor authentication (2FA) wherever it is offered.
  • Never share passwords by message or email, and never type them into a page you reached from a suspicious link.

Frequently asked questions

Is this password generator safe?

Yes. Passwords are generated in your browser using the Web Crypto API (crypto.getRandomValues). They are never sent to a server, stored, or logged.

How long should my password be?

At least 16 characters is a strong default in 2026. Longer is better — 20 or more characters makes a password dramatically harder to crack.

Should I include symbols?

Yes when a site allows them. Mixing uppercase, lowercase, numbers and symbols increases the pool of possible characters and raises strength. If a site rejects symbols, increase length instead.

Can I use the same generated password everywhere?

No. Generate a unique password for every account and store them in a password manager. Reusing one password means one breach unlocks everything.

What does the strength meter mean?

It estimates entropy — how many guesses an attacker would need. It is based on password length and the size of the character pool you enabled.

Do you store the passwords I generate?

Never. The password exists only in this page on your device. When you leave or refresh, it is gone — copy it into your password manager right away.

Short answer: Generate strong, random passwords (8–64 characters, with numbers and symbols) in one tap — created offline in your browser, never sent anywhere.

Frequently asked questions

Are my passwords sent anywhere?

No. Passwords are generated offline in your browser using your device's random number generator — nothing is transmitted or stored.

How long should my password be?

16+ characters with symbols is a strong default. Longer is always better for important accounts.

Is this safe to use for banking?

The password itself is cryptographically random, but always store it in a password manager — never reuse passwords.

Does it work offline?

Yes. Once the page loads, it works with no internet connection at all.

Can I generate a password with letters and numbers only?

Yes. Untick Symbols and keep Uppercase, Lowercase and Numbers switched on — you get a letters-and-numbers-only password at any length from 8 to 64 characters. Handy for sites that reject special characters.

Do I need to sign up to use this password generator?

No. This password generator needs no signup and no account — open the page and generate instantly. Everything runs offline in your browser, and nothing is ever stored or sent anywhere.
