Frequently asked questions
What is a UUID v4?
A UUID v4 is a 128-bit identifier where the value is generated from random numbers. It looks like 550e8400-e29b-41d4-a716-446655440000.
How random are these UUIDs?
They are generated with crypto.randomUUID() in your browser, which uses cryptographically secure random values.
Are UUIDs unique?
Effectively yes. The chance of generating the same UUID twice is so small it is considered negligible in practice.
Is anything sent to a server?
No. UUIDs are generated locally in your browser. Nothing is uploaded.
