What Makes a Password Strong?
Password strength is determined by entropy — the amount of randomness or unpredictability. Higher entropy means exponentially more combinations for an attacker to try. The key factors are length and character set diversity.
Character Set Sizes
| Character Type | Size | Example |
|---|---|---|
| Lowercase only | 26 | abcxyz |
| + Uppercase | 52 | aAbBxXyY |
| + Numbers | 62 | aA1bB2 |
| + Symbols | 95 | aA1! @# |
Estimated Crack Times
| Password Length | Lowercase Only | Mixed + Symbols |
|---|---|---|
| 6 characters | Under 1 second | 5 seconds |
| 8 characters | 2 hours | 8 years |
| 12 characters | 3 centuries | 34,000 years |
| 16 characters | Millions of years | Billions of years |
Assuming 100 billion guesses per second (modern GPU cracking speed).
Password Best Practices
- Use at least 12 characters — length matters more than complexity
- Use a passphrase: 4+ random words are stronger than a short complex password
- Never reuse passwords across sites
- Use a password manager (Bitwarden, 1Password, Dashlane) to generate and store unique passwords
- Enable two-factor authentication (2FA) wherever available
