If you want random number sets with duplicates allowed try the Random Number and Letter Set Generator. Generate a Random Number for a PIN. To generate a 4 digit PIN without duplicate digits, choose Min = 0, Max = 9 and Generate 4 Numbers. Example: 4 digit PIN without duplicates. Algorithmic random number generation can’t exactly be random, per se; which is why they’re more aptly called pseudo-random number generators (PRNGs). If you’re using math and formulae to create a sequence of numbers, random though they might seem, those numbers will eventually repeat and reveal a non-random pattern.

Random Number Generator

Its the core of all randomness. Pick a number or generate a whole sequence of numbers within a minimum and maximum value (inclusive) while including or suppress duplicates. Your device is used to quickly generate these numbers, completely random and unique to you every time.

Change the quantity to one if you just want it to pick a number.
