Random Generator: Numbers, Dice, Coins, and Passwords

Generate random numbers within a range, roll dice, flip a virtual coin, or create secure random passwords. Useful for games, decision-making, testing, and generating credentials.

Formula

For numbers: random integer between min and max inclusive. For dice: random 1-6. For coins: random heads/tails (50/50). For passwords: random characters from a 68-character set of letters, digits, and symbols.

Worked example

Random number 1-100: 42 (changes each time). Dice roll: 5. Coin flip: Heads. Password (12 chars): "k9#mP2$xL@v7" (changes each time).

Practical guidance

Use cases for random generation

Decision-making with coin flips, game dice rolls, random assignment in A/B testing, generating placeholder data for development, and password creation. For security-critical passwords, use a dedicated password manager.

Not cryptographically secure

This generator uses Math.random() which is suitable for games and casual use but not for cryptographic applications. For security tokens, encryption keys, or gambling systems, use a cryptographically secure random number generator.
