Unfortunately, Starbucks does not offer an online way to delete a Starbucks account. To cancel a Starbucks account after someone dies, you can reach out to Starbucks' customer service and ask them to disable it. They will be able to make the account information unusable in order to eliminate and reduce the risk of fraud. You should also delete the Starbucks app from any phones associated with the account. You can reach Starbucks' customer support line here.
