You've heard it a thousand times: "Use a strong password." But what does that actually mean in 2026, when attackers use GPU clusters testing billions of combinations per second?
The Old Rules Are Broken
Traditional advice said to use passwords like P@$$w0rd!2k — short, complex strings. Here's why that doesn't work:
- An 8-character complex password has ~6 quadrillion combinations
- Modern GPU clusters test 100 billion passwords per second
- Result: an 8-character password can be cracked in roughly 17 hours
Meanwhile, a 16-character lowercase password like correcthorsebattery would take the same cluster over 1,000 years.
Length Beats Complexity
Every additional character multiplies possible combinations exponentially:
- 8 characters (complex): crackable in hours
- 12 characters (mixed): crackable in years
- 16 characters (lowercase): crackable in millennia
- 20 characters (lowercase): effectively uncrackable
A 20-character lowercase password is orders of magnitude stronger than an 8-character password with every special character you can type.
The Passphrase Approach
The most practical way to create long passwords is passphrases — random words strung together. A four-word passphrase from a 7,776-word dictionary has about 1.6 × 10¹⁵ combinations. Five words: 2.8 × 10¹⁹. Memorable, typeable, and extremely strong.
What Actually Gets Passwords Cracked
- Password reuse: One breached site exposes all your accounts
- Phishing: Fake login pages that steal credentials
- Dictionary attacks: Testing common words and leaked passwords
- Social engineering: Guessing from personal info (birthdays, pet names)
Best Practices for 2026
- Use a password manager — unique 20+ character passwords for every account
- Enable 2FA — even compromised passwords can't access your account
- Never reuse passwords — every account gets a unique one
- Use passphrases for typed passwords — laptop login, master password
- Check for breaches — use haveibeenpwned.com
Generate Strong Passwords
- Open the Password Generator
- Set length (16+ characters recommended)
- Choose to include uppercase, numbers, symbols
- Click Generate
- Save in your password manager
