When the Random Number Generator is useful

How the Random Number Generator works
Numbers are drawn from your specified inclusive range using the browser's random number generator, and unique mode applies a draw-without-replacement strategy so the same value cannot appear twice in one batch. The range can span negative numbers or huge spans, and results appear immediately. Everything happens locally, so the draws cannot be influenced by any server.
Limits to keep in mind
The generator suits games, drawings, and sampling; for cryptographic keys or tokens, use a dedicated cryptographic tool like the Password Generator.
