Frequently Asked Questions
What is a UUID?▼
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. Version 4 UUIDs are generated randomly and are practically guaranteed to be unique.
Are these UUIDs safe to use?▼
Yes. They are generated completely offline using your browser's built-in crypto.randomUUID() function, which is cryptographically secure. Nothing is uploaded to our servers.
