Are these random results truly random?
Each tool uses your browser's standard random number generator, which produces a uniform, unbiased distribution suitable for games, raffles, and everyday decisions. It is not a cryptographically secure random number generator (CSPRNG), so it shouldn't be used for passwords, encryption keys, or security tokens.
