Frequently asked questions
Do these UUIDs contain a creation timestamp?
No. These are random version 4 UUIDs. Store creation time in a separate field when needed.
Can knowing a UUID be treated as authorization?
No. Identifiers may appear in URLs and logs. The receiving application must enforce its own access checks.
