To remove the prompts of the presence of verification required at the app store, use this step-by-step tutorial first, open Settings > Apple ID > Payment and Shipping and change or delete an expired card. You should then go to Purchase History and remove unpaid transactions on your account. Then navigate to Screen Time / iTunes and App Store Purchases and disable the Requirement Password option so as not to be re-authenticated. Lastly, log out of your Apple ID and log in. After these measures are implemented, you will effectively be ridding yourself of verification that must be done on app store and making the usage of apps a simple affair.
