| 10 characters, all types | ≈ 6 × 10¹⁹ | About 200 years |
| 12 characters, all types | ≈ 5 × 10²³ | Millions of years |
| 16 characters, all types | ≈ 4 × 10³¹ | Far longer than the age of the universe |
| 4 random words | ≈ 1.8 × 10¹³ | Under an hour (use 5+ words) |

| 6-digit PIN | 1,000,000 | Instant offline — PINs rely on lock-outs |
