Frequently asked questions
What's the difference between with and without repeats?
Without repeats (unique) works like drawing raffle tickets from a hat — once a number comes up, it's removed from consideration. With repeats works like rolling a die each time — any number can come up again, independent of previous results.
Is this suitable for anything security-sensitive?
No — this uses your browser's standard random function, which is fine for games, raffles, and general sampling, but not suitable for generating passwords, encryption keys, or anything requiring cryptographic randomness.
