How to Create an Unbreakable Password (With Examples)

Creating a strong password doesn't have to be complicated — but it does require following some key principles. Here's a straightforward guide to passwords that will actually keep hackers out.

Length Is King

The single most important factor in password strength is length. Each additional character exponentially increases the time needed to crack a password. Aim for at least 16 characters — longer is always better.

Use a Mix of Characters

Combine uppercase and lowercase letters, numbers, and special characters. But avoid predictable patterns like 'A1b2C3!' — randomness matters more than variety.

The Passphrase Method

One of the best approaches is using a passphrase — a sequence of random, unrelated words.

Example: 'Mountain$Cloud9Pencil!Drum'

This is long, complex, and much easier to remember than a string of random characters — but just as strong or stronger.

Never Use Personal Information

Avoid names, birthdays, pet names, favorite sports teams, or any information that could be found on social media. Hackers often research their targets before attempting to guess passwords.

Make Every Password Unique

Use a different password for every account. Yes, that sounds overwhelming — but that's where password managers come in. Tools like Bitwarden, 1Password, or Dashlane generate and store unique passwords for you, so you only need to remember one master password.

Check If Your Password Has Been Leaked

Visit websites like haveibeenpwned.com to check if your email or passwords have appeared in known data breaches. If they have, change them immediately.

Strong Passwords Are Just the Start

Even the best password benefits from a second layer of protection. Enable two-factor authentication (2FA) on every account that supports it — which we'll cover in the next blog.
