FAQ

Is this truly random?

Yes. We use the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same source used for TLS encryption.

Can I generate numbers without duplicates?

Yes. Check "No duplicates" and the generator will produce unique numbers only. The quantity is automatically limited to the available range.

What dice types are supported?

D4, D6, D8, D10, D12, D20, and D100 — covering all standard tabletop RPG dice. Roll up to 20 dice at once.

How strong are the generated passwords?

Very strong. They use crypto-secure randomness with customizable length (4–64 chars) and character sets (uppercase, lowercase, digits, symbols). A 16-character password with all sets is virtually uncrackable.
