Frequently asked questions

Questions about UUID Generator

What is a UUID?

A UUID is a 128-bit identifier designed to be unique across systems without requiring a central coordinating service. UUIDs are commonly used as database keys, API identifiers, request IDs, and identifiers in distributed applications.

What is UUID v4?

UUID version 4 is generated primarily from random data. Its version and variant bits follow the UUID format, while the remaining bits are generated securely. A UUID v4 looks like 550e8400-e29b-41d4-a716-446655440000.

Can two generated UUIDs ever be the same?

A collision is theoretically possible, but extraordinarily unlikely when UUID v4 values are generated correctly with cryptographically secure randomness.

Are UUIDs generated on Avorqin sent to a server?

No. UUID generation happens locally in your browser using secure browser cryptography APIs. Avorqin does not need to send generated UUIDs to an external API.
