How to Create a Strong Password (and Remember It)

4 min readUpdated 5 October 2026

A strong password is long, random and used for one account only. The quickest way to make one is Password Generator: it creates a 20-character random password the moment it opens — press Copy and save it in your password manager. For a password you must type or remember, switch to Passphrase for a string of random words.

The generator is free, needs no sign-up and works in any browser. Passwords are made with your browser's cryptographically secure random generator, right on your device, and are never sent anywhere or saved to History.

Step by step

  1. 1Open Password GeneratorGo to the Password Generator. A fresh random password is already waiting, so there is nothing to set up.
  2. 2Pick Password, Passphrase or PINUse Password for anything stored in a password manager, Passphrase for the few you need to remember, and PIN only where attempts are limited, such as a phone or bank card.
  3. 3Set the length and charactersDrag Length (6 to 128) or tap a preset such as 16 or 20. Keep Uppercase, Lowercase, Numbers and Symbols on unless a site rejects some, and turn on Avoid look-alikes if you will ever read it aloud or type it by hand.
  4. 4Check the strength meterThe meter shows the strength in bits and a rating from Weak to Excellent. Aim for Strong or Excellent; length raises it faster than anything else.
  5. 5Copy and store itPress Copy (or the C key) and paste it straight into your password manager or the site's sign-up form. Regenerate (Space or Enter) gives you a new one; Generate 10 shows a list to choose from.

What makes a password strong

Strength comes from how many guesses an attacker would need, and length adds far more than clever substitutions. “P@ssw0rd!” looks complex but follows patterns that cracking tools try first; a random 16-character string or a five-word random phrase is much harder to guess.

Randomness matters as much as length. Names, birthdays, phone numbers, football teams and keyboard runs like “qwerty” are easy to guess, even when you add a number at the end. Let a generator pick the characters instead of choosing them yourself.

Passphrases: strong passwords you can remember

A passphrase strings together random everyday words, such as “Maple-Rocket-Quilt-Harbor-Lemon7”. It is easy to type on a phone and easy to remember, yet still hard to guess because the words are picked at random.

In Passphrase mode, choose the Word count (3 to 10), a Separator, and whether to Capitalise words and Add a number. The words come from a list of about a thousand common English words, so use six or more words for important accounts — check that the meter reads Strong.

Tip: Use a passphrase for the few passwords you type from memory: your computer login, your password manager and your main email.

Habits that matter more than any single password

A perfect password still fails if it is reused or stolen. These habits do most of the work:

  • One password per account. When one site is breached, attackers try the same email and password everywhere else.
  • Use a password manager. It remembers every password, fills them in for you and warns you about reused ones, so you only remember one strong passphrase.
  • Turn on two-factor authentication (2FA), especially for email, banking and social accounts. An authenticator app is safer than SMS where you have the choice.
  • Change a password when there's a reason — a breach notice, a shared device, or a password you've reused — rather than on a fixed schedule.
  • Never share passwords in chat or email, and be wary of links asking you to “verify” your account.

When a site rejects your password

Some sites still limit length or ban certain symbols. Lower the Length to their maximum, or switch Symbols off and add a few more characters to make up for it — a longer password without symbols can be just as strong.

For developers who need random secrets rather than human passwords, Cron Secret Generator makes API-style keys, UUID Generator makes unique IDs, and Hash Generator creates SHA-256 checksums.

Questions people ask

How long should a password be?
At least 12 characters for a random password, and 16 or more is better for important accounts. The generator starts at 20, which is comfortable when a password manager fills it in for you.
Is it safe to use an online password generator?
This one is: passwords are created in your browser with a cryptographically secure random generator and never leave your device. Generated passwords are not saved to History — only your settings are.
Are passphrases as secure as random passwords?
They can be, if the words are chosen at random and there are enough of them. Six or more random words is strong for most uses, and much easier to type than a jumble of symbols.
Should I change my passwords regularly?
Not on a timer. Change a password if it may have been exposed, if you reused it elsewhere or if someone else knows it. Unique passwords plus 2FA protect you better than frequent changes.
