What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across all devices and time. UUIDs are commonly used as primary keys in databases, session IDs, and API request identifiers.
This tool generates UUID v4 identifiers using the browser's built-in crypto.randomUUID() API for cryptographically secure random generation.
