The unexpected thing when I put WhatsApp on the new phone was that old messages weren't readable. They needed to do a key exchange with other participant but it never seemed to ever render. That was about the biggest inconvenience. If I hadn't installed WhatsApp on the new phone, I could keep reading old messages on web app. So it's good to grab the info you need before taking that step.
Today I had breakfast by myself without any devices. I was just looking out the window at nature. Quite a different and refreshing experience. (Even as a kid I used to read and reread the cereal boxes at breakfast.)
I am very close to giving up and buying 2 or more working phones at any time, for the same reason I keep a spare tire in the trunk. I would love to see google's Pixel program try this, where you get 2 phones, but are only charged if you activate the spare.
It's is troubling to see Steve Job's dream come to it's full realization- these phones are not a luxury, or even a commodity. Living without a smartphone today is basically impossible.
Microsoft Authenticator is the biggest offender that comes to mind - without it, I cannot work. My company requires that we share our location to access systems (it's to enforce compliance controls that data stays in the country), so I can no longer use an offline MFA strategy like a U2F token or a TOTP key - I _have_ to use Microsoft Authenticator.
How much more complicated will this all get? How much can it?
Digital identity should be a physical smart card, as has been the case for decades with mobile phone SIM cards, bank cards, etc every ID document and each of these, where issued by the public sector, should form part of a federated system of public administration ID that provides authentication services to citizens.
Digital signatures should be a key stored on the smart card, not a third-party guarantor using SMS OTP, scanned signatures, or other absurd analogues.
Yet this is not the case because most IT professionals know nothing and attempt to reconstruct with IT what they only understand through paper, thereby creating opportunities for a few to profit greatly from their ignorance, and nothing more.
