UUIDs & tokens

A UUID v4 is a 128-bit identifier built from random data, designed to be unique without any central coordination — the standard choice for random IDs. The token option gives you a URL-safe random string handy for API keys and session secrets. Both use your browser's cryptographically secure random source.
