I received the attached email earlier today. I deliberately do not have FaceID enabled because of the following:
When FaceID fails it degrades back to your iPhone passcode, ie you can overrule FaceID with a passcode.
This means that, in the doomsday scenario of someone having access to my phone and the passcode (either by looking over my shoulder when I enter my passcode or, more likely, mugging me and asking me for it, which is fairly common), they can not only access my phone but they can make payments out of Monzo, because they can use the passcode to overrule FaceID.
But, if you still require use of your PIN, you have a second layer of security.
Am I missing something here? If not, why is Monzo encouraging the use of FaceID when you could argue it makes your account less secure? Or are these communications actually coming from the product side of the business, which presumably is more interested in faster payments (typing in your PIN is a pain!), rather than account security?
