Frequently asked questions

What is a UUID?

A Universally Unique Identifier — a 128-bit value usually shown as 8-4-4-4-12 hex (e.g. 550e8400-e29b-41d4-a716-446655440000). Very low collision probability.

Which version do you generate?

UUID version 4 (random). Suitable for unique IDs in databases, APIs, and distributed systems.

Are UUIDs cryptographically random?

UUID v4 uses random bits. For security-sensitive use (e.g. tokens), prefer a dedicated secure random token generator.
