    Preguntas frecuentes

    Quick answers.

    ›How secure are these random values?

    The generator uses `crypto.getRandomValues()`, which is a cryptographically strong source of entropy provided by your browser. This makes the output suitable for use-cases requiring high unpredictability, such as tokens or temporary secrets.

    ›What is a UUID?

    A Universally Unique Identifier (UUID) is a 128-bit label used for identification in software systems. We generate Version 4 UUIDs, which are constructed entirely from random numbers.

    ›Can I generate multiple values at once?

    Yes. You can specify the 'Count' field to generate a list of numbers or strings in a single batch for bulk processing.

    ›Is my data logged?

    No. Because the generation occurs within your browser's memory, no record of the generated strings or numbers exists on our servers.
