Thanks for the reply! The customer doesn't have the chance to sign out of Paypal. I used my personal Paypal account, with Auto Login and One Touch disabled, and a Firefox browser set to not store passwords, made a purchase from the company's website, and after payment was immediately returned to the company's website. I then opened a new window on my browser and went to Paypal.com, where I found I was not logged in. I returned to the company's website, and went to make another purchase using Paypal. My account's payment information was immediately presented without my logging into Paypal. For now, we are advising customers not to use their Paypal account to make purchases on our shared computer, but instead to use the guest checkout feature on Paypal to pay with their credit or debit card, preferrably on their phone or home computer. For the future, we hope Paypal will address this and provide a way to force log out. Thanks again, Peter
