Frequently asked questions

Which UUID version does it generate?

Version 4, the random one. It is the version you want for database keys, session identifiers and anything that must not collide.

Can two generated UUIDs ever be the same?

In practice, no. A v4 UUID has 122 random bits: the chance of a repeat is so small it is not a risk worth planning for.

Are they generated on your server?

No. They are created in your browser with the Web Crypto API, so the values never travel anywhere.
