About UUID v4
UUID version 4 identifiers are generated using random values and are commonly used as unique identifiers in databases, APIs, distributed systems, and applications.
Because UUIDs contain 128 bits of randomness, the probability of generating duplicate identifiers is extremely small.
This generator uses the browser's built-incrypto.randomUUID()API, which provides cryptographically secure UUID v4 values.
