What version is generated?

The tool generates version 4 UUIDs using your browser's cryptographic random-number interface.

Collisions are astronomically unlikely for responsibly generated v4 values, but they are not mathematically impossible.

Should UUIDs be secret?

They are not passwords or authorization tokens. Treat any UUID that grants access as sensitive regardless of format.
