How to Create a Strong Password
Most password advice is outdated. “Use a capital letter, a number and a symbol” produces passwords that are hard for you to remember and easy for computers to guess. Modern security research points somewhere simpler: length beats complexity. This guide explains what actually makes a password strong and how to create one you can rely on.
What makes a password strong (and what doesn’t)
The single biggest factor is length. Each extra character multiplies the number of combinations an attacker has to try. A long password is exponentially harder to crack than a short one, regardless of how many symbols you sprinkle in.
What doesn’t help much:
- Predictable substitutions.
P@ssw0rdisn’t fooling anyone — attackers’ tools try those swaps automatically. - A single word plus a number.
Summer2026!matches an extremely common pattern. - Reusing a “strong” password everywhere. One breach then unlocks every account.
Length over complexity: the passphrase
A great, memorable option is a passphrase — several random, unrelated words strung
together, like copper-lantern-drift-oyster. It’s long (so it’s hard to crack) but easy for
a human to remember, unlike X7#kq2!p. Four or more random words is genuinely strong.
For accounts you never type by hand — most of them — a fully random string from a generator is even stronger, since you’ll store it in a password manager anyway.
Generate a strong password in your browser
Our free Password Generator creates random passwords entirely in your browser — nothing is sent anywhere, so the password you generate is only ever seen by you.
- Open Password Generator.
- Set the length — aim for at least 16 characters (longer for important accounts).
- Choose the character types (letters, numbers, symbols) your target site allows.
- Generate and copy it straight into your account or password manager.
Because it runs locally, the generated password never travels over the network.
Habits that matter more than the password itself
- Use a unique password per account. This is the most important rule. A breach on one site should never endanger the others.
- Use a password manager. It remembers long, unique passwords so you don’t have to. Then you only need to memorise one strong master passphrase.
- Turn on two-factor authentication (2FA). Even a leaked password is far less dangerous when a second factor is required.
- Change a password only when you need to — after a breach, or if you suspect exposure. Forced routine changes tend to make people pick weaker, patterned passwords.
Common questions
“How long should a password be?” At least 16 characters for anything that matters. For a passphrase, four or more random words.
“Do I need symbols and numbers?” They add some strength, but length matters more. Include them if a site requires them — don’t rely on them to rescue a short password.
“Is it safe to use an online generator?” It’s safe when the tool runs in your browser and never sends the password anywhere — like ours. Avoid generators that transmit or log results.
The short version
Make it long — 16+ characters or a four-word passphrase — keep it unique per account, and store it in a password manager with 2FA switched on. Generate it locally so it never leaves your device.
