    What is a UUID?

    UUID stands for Universally Unique Identifier. It is a 128-bit number used to uniquely identify objects or information in computer systems. UUIDs are widely used in software development, databases, APIs, and distributed systems to create unique keys or identifiers that are globally unique.

    A UUID looks like this: f47ac10b-58cc-4372-a567-0e02b2c3d479. It consists of five groups of hexadecimal digits separated by hyphens.

    Why Use a UUID Generator?

    • Global Uniqueness: UUIDs reduce the risk of duplication across systems, projects, or databases.
    • No Central Authority Needed: UUIDs can be generated independently without coordination.
    • Security: Version 4 UUIDs are randomly generated, offering strong unpredictability.
    • Scalability: Ideal for distributed systems, microservices, and decentralized environments.
    • Easy Integration: Use UUIDs in databases, APIs, tokens, or anywhere unique IDs are needed.
