What is UUID Generator?

A UUID (Universally Unique Identifier) is a 128-bit label used for identifying information in computer systems. Version 4 UUIDs are randomly generated and provide an incredibly high guarantee of uniqueness, making them perfect for primary keys in databases, session tokens, or transaction IDs. The probability of a collision is practically zero.
