What is a UUID / GUID?
A Universally Unique Identifier (UUID) or Globally Unique Identifier (GUID) is a 128-bit label used for information in computer systems. Version 4 UUIDs are generated using random or pseudo-random numbers, ensuring the probability of a duplicate is practically zero.
Hardware-Level Cryptography
ZeroServer utilizes your browser's native crypto.randomUUID() API. This ensures that every identifier is generated using mathematically secure, hardware-backed entropy, making it perfectly safe for database keys and secure session IDs.
