Example
Worked example: 6-digit OTP simulation batch
- 1 Set length to 6.
- 2 Set count to 10.
- 3 Generate and export results to your test fixture file.
The tool produces 10 random 6-digit values such as 942103 and 017284.
How
- Choose PIN length and batch count.
- Enable unique mode if duplicates are not allowed.
- Generate and copy results as newline-separated values.
Avoid
- Requesting more unique PINs than mathematically possible for a selected length.
- Using PIN output as production credentials instead of temporary or test values.
- Forgetting that leading zeros are valid in fixed-length PIN workflows.
