When shopping online, it would be nice to be able to approve purchases via a notification on the Apple Watch instead of needing to grab the phone, open the app, and approve.
I don’t think authentication on a watch would meet the 3DS regs
I have a similar app at work whereby the app authenticates, I presume, using the device but I can tap to approve on the Watch.
Major savings there. So, regulations dependant, I would love to see this happen
