How to Create Strong Passwords That Are Hard to Crack
A weak password is an open door for hackers. In this guide, we explain the science behind strong passwords and show you exactly how to create them — and remember them.
Why Password Strength Matters
Data breaches expose billions of passwords every year. Hackers use automated tools that can test millions of password combinations per second. A short, simple password can be cracked in seconds. A strong, random password could take longer than the age of the universe.
What Makes a Password Strong?
Security experts agree on several key factors:
- Length: At least 12 characters — 16 or more is ideal
- Complexity: Mix uppercase, lowercase, numbers, and symbols
- Randomness: Avoid predictable patterns or personal information
- Uniqueness: Use a different password for every account
Common Password Mistakes to Avoid
- Using dictionary words or common phrases
- Using personal information (name, birthday, pet name)
- Sequential characters (123456, abcdef)
- Reusing passwords across multiple sites
- Passwords shorter than 8 characters
How to Create a Strong Password
The easiest way is to use a password generator. Our free Password Generator tool creates cryptographically secure, random passwords instantly. Just set your desired length, choose your character sets, and click Generate.
Alternatively, you can create a passphrase: pick 4-5 random words and connect them. For example: correct-horse-battery-staple is much stronger than P@ssw0rd! and easier to remember.
Storing Your Passwords Safely
Never write passwords on sticky notes or store them in plain text files. Use a reputable password manager to store and auto-fill all your unique, strong passwords. Popular options include Bitwarden, 1Password, and Dashlane.
