I've been a happy ebayer for 17 years. Recently they added a new security verification process and I got locked out of my account. No way of getting through to them, so asked someone to send them an email explaining my problem.
After a lot of hassle I managed to speak to someone: No smart phone, no way of getting into my account. Byeeee.
This is the start. More places going cashless in the UK. If you don't comply you are out of the system.
I back up my phone every week. It's a Samsung so I use "SmartSwitch" app.
But I take most photos with a camera and upload them to my computer every day.
