    Frequently asked questions

    Are generated UUIDs random?

    UUID v4 uses secure browser randomness; UUID v7 combines a millisecond timestamp with secure randomness.

    Can UUIDs identify a person?

    UUIDs are identifiers, not proof of identity. Avoid putting sensitive information into identifiers.
