Numeric password security by length
| Digits | Combinations | Crack time (online*) | Use case |
|---|---|---|---|
| 4 | 10,000 | Seconds | Basic PIN — avoid for sensitive accounts |
| 6 | 1 million | Minutes | OTP codes, basic verification |
| 8 | 100 million | Hours | Acceptable with rate limiting |
| 10 | 10 billion | Days | Good for numeric-only systems |
| 16 | 10 quadrillion | Centuries | Strong — use when forced numeric |
* Online attacks with rate limiting (10 attempts/second). Offline attacks (data breach) are 10 billion guesses/second or faster.
Numeric passwords are inherently weaker than alphanumeric ones because the character pool is only 10 digits. Always use the longest numeric password a system allows. If a system accepts both numeric and alphanumeric, choose alphanumeric — use our full generator for those.
