How the uuid generator works
A UUID v4 is a 128-bit identifier with 122 random bits, formatted as 32 hex digits in 5 groups (e.g. 550e8400-e29b-41d4-a716-446655440000). The '4' marks the version.
Collision odds are astronomically low — you would need to generate billions per second for a century to expect one duplicate. Generation here uses your browser's random number generator; nothing leaves your device.
