4-Digit Random Number / Code Generator, FAQ

How do I use the 4-Digit Random Number / Code Generator?
Set your options if you like, then press Generate. You'll get a 4-digit code instantly, ready to copy. Sensible defaults mean you can also just hit Generate.
Will the code always be four digits?
Yes, shorter numbers are padded with leading zeros, so you always get a full four-digit code like 0421 or 9037.
Are these codes secure enough for real accounts?
They're great for demos and one-off codes, but for account security use our Password Generator instead.
Is the 4-Digit Random Number / Code Generator really random?
Yes. Where available, Toolssy uses the browser's Web Crypto API, far stronger than a basic Math.random() call, so your 4-digit codes are genuinely unpredictable and unbiased.
Is the 4-Digit Random Number / Code Generator free, and do you store my results?
It's completely free with no account and no limits, and no, nothing is stored. Everything runs locally in your browser, so your inputs and results are never sent to a server or logged.
