The user experience of lots of things is terrible if the relevant facilities aren't set up on the device you want to use at the time. It's a curse of our modern, highly-connected and always-online world. You get the same problem with logging into sites that require ID and password from a device that doesn't have your password manager on it. But the fact is, many systems do work like that and many users do prefer it. I'm taking a pragmatic stance here because assuming the messy, unpredictable real world always follows some theoretical standards at a scale of billions of people and millions of organisations is very predictably going to give bad results in a lot of cases.
