Frequently Asked Questions
Are the generated UUIDs truly random?
Yes. UUIDs are generated using the Web Crypto API (crypto.randomUUID or crypto.getRandomValues), which provides cryptographically secure random numbers.
What is the difference between UUID and GUID?
UUID (Universally Unique Identifier) and GUID (Globally Unique Identifier) are the same thing. GUID is the term used primarily by Microsoft, while UUID is the standard term used in RFC 4122.
Can generated UUIDs collide?
The probability of a UUID v4 collision is astronomically low — about 1 in 2^122. For practical purposes, collisions will never occur.
