​If you'd like your customers to not have the option of saving their checkout information, you can set your store to allow Guests only. Note that a subscription product type will require the customer to save a password since you need to save the payment information to process recurring payments automatically - Go to your Foxy administration templates configuration page here: https://admin.foxycart.com/admin.php?ThisAction=TemplateConfig - Scroll to “Customize the checkout user type (account vs. guest)” and check the box to reveal your options - Under “checkout type” select “Allow guests only” - Scroll down and click “Update” to save

Past saved customers will no longer be prompted to enter a password and new customers will not be prompted to save a password.
