How it works

A cryptographically secure random source selects decimal digits, allowing repeats unless a constraint explicitly forbids them. The search space is 10 to the power of the PIN length before rate limits and throttling are applied.

  • Decimal digits match keypad entry; length and attempt limits provide the protection.

Worked example

Count: 1
Allow repeating: true
Output
												986948

When to use this

Device setup, support workflows, and numeric authentication fixtures generate PINs.

Edge cases

  • A sequential PIN is predictable despite having four digits.
  • Disallowing repeated digits reduces the available combinations.
  • A PIN without attempt throttling is vulnerable to online guessing.
