Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across all devices and time. UUID v4 uses random numbers and has a collision probability so low it's practically zero.
Are these UUIDs truly random?
Yes. RawDev uses the Web Crypto API (crypto.randomUUID()), which provides cryptographically secure random number generation built into your browser.
