What is a Uuid?

A UUID (Universally Unique Identifier) Generator creates random 128-bit identifiers in the standard UUID v4 format. These IDs are cryptographically random and statistically guaranteed to be unique, making them ideal for database primary keys, session tokens, tracking IDs, and distributed system identifiers.
