As the Journal notes, several states have proposed sweeping age verification measures, at least nine of which specifically place the burden for checking ages on app stores; one state, Utah, has such a law already passed.
The law will require users who are under the age of 18 to receive parental consent to download apps or make in-app purchases, according to Reuters.
An Apple spokesman told the Journal the company wants to strengthen online safety for children but that the Texas bill threatens user privacy.
