Frequently asked questions
What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit identifier used to guarantee uniqueness without a central coordinating system.
What is the collision probability of two UUIDs v4?
The probability is so incredibly low that it is considered virtually zero. You would need to generate billions of UUIDs per second for centuries to have a real collision risk.
Does this tool generate secure UUIDs?
Yes. It uses the browser's native cryptographic API (crypto.randomUUID) for high randomness.
