Learn password security best practices and how to generate strong, unbreakable passwords using our free password generator.
Weak passwords are the #1 cause of data breaches. In 2024, over 80% of hacking-related breaches involved stolen or weak credentials.
What Makes a Password Strong?
A strong password should include:
- Length: At least 16 characters (12 minimum)
- Uppercase letters: A-Z
- Lowercase letters: a-z
- Numbers: 0-9
- Symbols: !@#$%^&*()_+-=
- No dictionary words: Avoid common words and phrases
Password Strength by Length
| Length | Characters | Possible Combinations | Time to Crack* |
|---|---|---|---|
| 8 chars | 94 | 6.0 × 10¹⁵ | 5 hours |
| 12 chars | 94 | 4.8 × 10²³ | 34,000 years |
| 16 chars | 94 | 3.9 × 10³¹ | 2.7 × 10¹⁶ years |
| 20 chars | 94 | 3.2 × 10³⁹ | 2.2 × 10²⁴ years |
*Assuming 10 billion guesses per second
Common Password Mistakes
- Using personal info — birthdays, pet names, addresses
- Reusing passwords — one breach compromises all accounts
- Simple substitutions — "P@ssw0rd" is just as weak as "Password"
- Short passwords — anything under 12 characters is risky
- Using patterns — "123456", "qwerty", "abcdef"

- Use a different password for every account
- Use a password manager to store passwords securely
- Enable 2FA (two-factor authentication) on important accounts
- Generate passwords with our tool instead of creating them manually
