You can also remove saved payment methods from your Microsoft account, although this may affect subscriptions. Switch off ‘Allow sites to check whether you have payment methods saved’. To stop saved cards being automatically filled at the online checkout, go back into Settings and this time search for ‘payment’. To be clear, you’ll still need to enter the CVC or three-digit security code on the back of the card to process a payment, but on a shared family computer, for example, it makes it much easier for someone to use payment details without permission. Worse, if you get to the payment section of websites, Edge offers to automatically fill in those payment details. Now, if you sign into the Edge browser with your Microsoft account, as Microsoft urges you to do, those payment methods are automatically synced to the browser. If you have payment methods saved with Microsoft - because you have an Xbox account or Office 365 subscription, for example - these are automatically linked to your Microsoft account.

Microsoft does something incredibly irritating and potentially costly with Edge.
