Frequently asked questions
Questions about UUID Generator
What is a UUID v4?
UUID v4 is a randomly generated 128-bit identifier represented as hexadecimal characters separated by hyphens.
Are UUIDs guaranteed to be unique?
Absolute uniqueness cannot be mathematically guaranteed, but the probability of a correctly generated UUID v4 collision is extraordinarily small.
Is a UUID suitable as a password or secret?
No. UUIDs are identifiers, not authentication secrets. Use a dedicated cryptographically secure token format for passwords, API keys or session secrets.
Are the generated UUIDs uploaded?
No. UUID generation occurs entirely inside your browser.
