Dice Roller
Use Dice Roller to roll one or more six-sided dice — free, immediate, and with nothing to install. Values come from the browser's built-in cryptographic random generator (Web Crypto), not a predictable pseudo-random function. It is used most by anyone replacing a reused password with something unguessable. Generated values exist only in your tab and are never transmitted or stored. There is no account to create, no email to hand over and no cap on how often you use it.
Key features
- Nothing is remembered, so copy the value before leaving the page.
- Uses crypto.getRandomValues — the same source browsers use for real cryptographic work.
- Works on desktop, tablet and phone — no separate app to install.
- No ads interrupting the tool itself, and no upsell before the result.
How to use Dice Roller
- Set your requirements: Choose the length and which character types to include.
- Generate: Press the button — a fresh cryptographically random value appears immediately.
- Store it safely: Copy it into a password manager now. Nothing is kept once you leave the page.
Frequently asked questions
- Is the output from Dice Roller genuinely random? — Yes. Dice Roller uses the browser's Web Crypto generator, which is designed for cryptographic use — not the predictable Math.random.
- Is this safe for production keys? — The randomness source is appropriate for it. Handle and store the value with the same care as any other secret.
- Can the same value be generated twice? — At the lengths used here the chance is vanishingly small — far below anything that matters in practice.
- Could anyone else see the value? — No. It is created in your tab and never sent anywhere. Nothing is logged or stored.
