Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that's extremely unlikely to be duplicated. They're commonly used in databases, distributed systems, and anywhere unique identification is needed.
Which UUID version should I use?
Version 4 (random) is recommended for most uses as it provides the highest level of uniqueness. Version 1 can be useful when you need timestamp information embedded in the UUID.
Are these UUIDs secure?
Yes! All UUIDs are generated locally in your browser using cryptographically secure random number generation. No data is sent to any servers.
