With data breaches exposing billions of credentials and AI-powered cracking tools becoming cheaper, password security has never been more critical. Yet most people still use "Password123" or their pet's name. Here's how to create passwords that would take centuries to crack.
How Long Does It Take to Crack Your Password?
| Password Type | Example | Time to Crack (GPU) |
|---|---|---|
| 6 chars, lowercase only | monkey | Instantly |
| 8 chars, mixed case | MyDog123 | Minutes |
| 10 chars, mixed + symbols | P@ssw0rd! | Hours to days |
| 12 random chars | xK9#mP2$wQ7! | Decades |
| 16 random chars | dR7%kL9@nM3#pQ8& | Millions of years |
| 4-word passphrase | correct-horse-battery-staple | Hundreds of years |
Password Strength Rules
- Length beats complexity: A 16-character password using only lowercase is stronger than an 8-character password with symbols
- Minimum 12 characters for any important account (bank, email, social media)
- Never reuse passwords — one breach exposes all your accounts
- Avoid dictionary words even with substitutions (P@ssw0rd is in every cracking dictionary)
- No personal info: name, birthday, phone number — hackers check these first
Random Password vs Passphrase
Random passwords (e.g., xK9#mP2$wQ7!) are maximally secure but hard to memorize. Use these for accounts stored in a password manager.
Passphrases (e.g., purple-elephant-jumps-monday) are easier to remember and still very secure due to length. Use these for master passwords (password manager, laptop login) you must memorize.
Password Manager — The Real Solution
The only way to have unique, strong passwords for every account without going insane is a password manager. Top options: Bitwarden (free, open source), 1Password, Dashlane. Use a strong master password + 2FA on your password manager account — that's the only password you need to memorize.
Use our Password Generator to create cryptographically strong random passwords up to 128 characters. Uses the browser's crypto.getRandomValues() API — nothing is ever sent to any server.
