Estimated time to crack by brute force: instantly
Assumes 10 billion guesses/second — an illustrative upper-bound estimate. The real time depends heavily on the attack method, so treat this as a rough comparison, not a guarantee.

Why avoid sequential or repeating PINs?
PINs like 1234, 4321, or 0000 are among the very first guesses in any real-world attack, since they're disproportionately common. Filtering them out doesn't make an individual PIN mathematically stronger, but it does avoid the weakest, most-guessed patterns.
How many digits should I use?
Use whatever length the system you're setting the PIN for requires. Where you have a choice, longer is stronger — an 8-digit PIN has a search space 10,000 times larger than a 4-digit one.
