What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value used to identify records without a central authority. Version 4 is fully random, while version 7 embeds a millisecond timestamp so IDs sort by creation time — ideal for database primary keys.
Is it secure?
UUIDs are generated with your browser's cryptographically secure random number generator and never leave your device.
