Secure Random Generators for Passwords & More
Need a quick random decision? Roll dice, flip coins, pick random names, generate colors, or draw lottery numbers — all with cryptographically secure randomness. Perfect for games, giveaways, teaching, and creative projects.
Security starts with randomness. Generate unhackable passwords or transparent raffles. Our algorithms guarantee unpredictable and secure results for every need.
Blue Noise Point Distribution Generator
Generate high-performance distributions with Mitchell's Best Candidate algorithm.
Coin Flipper
Flip a virtual coin to make a quick decision.
Dice Roller
Roll one or multiple virtual dice for games.
Random Choice Picker
Pick a random item from a list of options.
Random Color Generator
Generate random colors in HEX, RGB, and HSL formats.
Random Fact Generator
Learn something new with interesting random facts.
Random Name Picker
Randomly select a name from your list.
Random Quote Generator
Get inspired with random quotes from famous people.
Rock Paper Scissors
Play a classic game of Rock Paper Scissors against the CPU.
Spaced Repetition Flashcards
Create, review, and schedule flashcards with local storage and JSON export/import.
Spin the Wheel
Create a custom wheel and spin it for random results.
Team Generator
Quickly split a list of names into random teams.
Choose the type of random output
Passwords, numbers, UUIDs, dice rolls, coin flips, raffle picks: each generator serves a different purpose. Use the password generator for security; use the raffle tool for transparency in group decisions.
Set your parameters
Length, character sets, ranges, number of results: configure the generator to match your requirements. More entropy means more security for passwords; simpler settings work for casual use.
Generate and review
Click generate. The tool uses the Web Crypto API for cryptographic randomness, not Math.random(). This matters for passwords and tokens where predictability would be a security risk.
Copy and use
Copy the result to your clipboard. For passwords, paste them directly into your password manager. Never share generated passwords over unencrypted channels.
Security-Conscious Users Generating Passwords
A strong password needs true randomness, not a pattern that feels random to a human. Our generator uses the Web Crypto API, which sources entropy from your operating system. The result is a password that cannot be predicted even by someone who knows the algorithm.
Teachers and Team Leads Running Fair Raffles
When you need to pick a name from a list and everyone needs to trust the result, transparency matters. Our raffle tool shows the randomization process so participants can see it was fair. No hidden seeds, no predetermined outcomes.
Tabletop Gamers Rolling Dice
Digital dice rollers with customizable sides and multiple dice at once. Roll a d20, roll 4d6 and drop the lowest, or simulate any combination your campaign requires. The results are cryptographically random, which is overkill for gaming but means the tool is always fair.

Yes; all generators are free with no limits on how many values you can generate.
Yes. We use the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same source of randomness used by HTTPS and other security protocols in your browser.
The randomness is cryptographically secure, which means it is unpredictable and unbiased. For legal contests, you may need to document the process; screenshot the tool in action as evidence of fair selection.
No. Generated passwords exist only in your browser's memory until you close the tab or generate a new one. We have no server endpoint that receives or logs generated values.
UUID generation is in the Data & Coding category. Our random generators focus on passwords, numbers, dice, and selection tools. Check the Data & Coding section for UUID v4 generation.
Math.random() uses a pseudo-random algorithm that is predictable if you know the seed. crypto.getRandomValues() uses entropy from the operating system, making the output unpredictable. For passwords and security tokens, this distinction is critical.
No, and that is by design. Cryptographic randomness cannot be seeded because seeding would make the output predictable. If you need reproducible pseudo-random sequences, use a library like seedrandom in your own code.
