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.
