FAQ

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify resources. UUIDs are designed to be globally unique without requiring a central authority.

Will I get duplicate UUIDs?

The probability of generating duplicate v4 UUIDs is astronomically low — about 1 in 5.3 × 10^36 for any two UUIDs to match.
