About UUIDs
What is a UUID?
A Universally Unique Identifier (UUID) is a 128-bit number used to
identify information in computer systems. Also known as GUIDs in Microsoft ecosystems.
Version 4 Security
This generator specifically creates v4 UUIDs, which are generated
completely randomly using cryptographically strong pseudo-random number generators (CSPRNG)
like
crypto.randomUUID().Collision Probability
There are 2122 possible v4 UUIDs. The chances of generating the same UUID twice is essentially zero. It's safe to use across distributed databases without synchronization.
