Common uses

Good practice
UUID v4 is suitable for many identifiers but is not automatically an authorization secret. Apply database constraints if uniqueness is required by the application.
Data handling
Generated identifiers contain random data rather than submitted personal content, but avoid treating a public UUID as proof of identity or permission.
