How to Create a Strong, Secure Password

Tap an item for practical habits that make a real difference in how secure your passwords actually are.

Why a long, complex password is safer

The longer a password is and the more it mixes letters, numbers, and symbols, the more exponentially longer a brute-force attack takes to crack it. A short 8-character password can fall within hours, while 12 or more well-mixed characters becomes practically unbreakable with current computing power.

Why you should never reuse a password across sites

When a password leaks from one service, attackers automatically try that same username-and-password combination on other sites β€” an attack called credential stuffing. A unique password per site means a breach in one place doesn't put your other accounts at risk.

A passphrase: easy to remember, hard to crack

A sentence built from three or four unrelated words, like "purple7bicycle!coffee", is both easy to remember and long enough to resist brute-force attacks. Mixing in random words plus a number and symbol gives you security and memorability at the same time.

Why you shouldn't include personal details

A birthday, phone number, name, or pet's name β€” anything easily found on social media β€” is one of the first things an attacker tries. This kind of information is especially vulnerable to a dictionary attack that automatically tests common words paired with personal details.

Critical accounts deserve extra-strong passwords

Accounts that could unlock financial loss or recovery of other accounts β€” email, online banking, cloud storage β€” deserve an especially long, unique password, ideally paired with two-factor authentication.

When it's actually worth changing a password

Rather than changing passwords on a fixed schedule for its own sake, it's more effective to change one immediately after learning a service you use was breached, or after a data-breach lookup service shows your details were exposed.

Passwords are still where security begins

Biometrics and passkeys are gaining ground, but most services still rely on a password as their default login method. Building the habit of creating a long, unique password remains the cheapest and most reliable way to prevent an account takeover.

If keeping track of every password feels impossible

A password manager solves the exact problem of needing a different password for every site: it generates a long, random password automatically, stores it securely, and fills it in for you, so you only need to remember one master password. Most also flag reused or weak passwords across your accounts, making it far easier to actually follow through on good habits.

Frequently Asked Questions

Do I really need to include a special character in my password?

A special character does expand the number of possible combinations, but in many cases simply making the password longer improves its strength more than adding one symbol does.

Isn't it too hard to remember a different password for every single site?

You don't need to memorize every one yourself β€” a password manager can automatically generate and store a unique, complex password for each site, which solves this problem entirely.
