"Who doesn’t use at least a few computers weekly?"
I don't. And many, many other people.
See what I did there? I assumed that everyone's like me, just like you did in your blog post. Without data, both of us are wrong.

I'd add that magic links also act as a distraction: you open your email client, and it by default opens your inbox, and you start going through all of those unread emails that you just found in your inbox...
Shopify is a big proponent for magic links because they went all-in on their new "Shop" customer accounts. What a disaster. Branding something with such a generic word as "shop" is terrible and average customer doesn't understand that it's supposed to be a brand name.
When you consider that a smartphone is "another" computer (or for many users, the computer that is not the smartphone is the "other" computer), I imagine that number goes way up. Someone using a computer at work and a personal phone, for example.
