About UUIDs

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. UUIDs are standardized by the Open Software Foundation (OSF).

  • UUID v4: Randomly generated, most common for general use
  • UUID v1: Includes timestamp and MAC address (not recommended for privacy-sensitive use)
