What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit value used to identify information in computer systems. It is a standard format for creating unique identifiers, ensuring that each identifier is unique across different systems and applications. UUIDs are often used in databases, file systems, and other systems to identify and track information.
About UUID version v4
Version 4 UUIDs are randomly generated identifiers. Their uniqueness relies entirely on the quality of the random number generator. With 122 random bits, the probability of collisions is negligible even at very large scales. They’re defined in RFC 4122.Disclaimer: UUIDs are not cryptographically secure. If you need secure tokens, use a CSPRNG or a library designed for authentication secrets. There is no guarantee of uniqueness for UUIDs generated by this tool.
