FAQ
What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit identifier used to uniquely identify information in computer systems. A UUID like 550e8400-e29b-41d4-a716-446655440000 is practically guaranteed to be unique.
Are generated UUIDs truly random?
UUID v4 uses cryptographically strong random values from the Web Crypto API, making them suitable for use as unique identifiers in distributed systems.
