What do v4 / v7 / v1 mean?
UUID v4

Fully random. The most common choice. 122 bits of entropy from a CSPRNG.

UUID v7

Time-ordered. 48-bit Unix millisecond timestamp + 74 random bits. Sorts naturally and is friendly as a database primary key.

UUID v1

Time-based with a node identifier. We use a random multicast node id, never your real MAC address, so nothing about your device leaks.

Generated entirely in your browser using the Web Crypto API. Nothing leaves your device.
