I creates a bar management/sales platform for our group of friends. It's self service so people purchase their products on their phone and pay later.
People get... intoxicated... after which passwords appear to become quite the problem. Magic links solved that.
To solve the multi device and in-app browser problem people can also open the links on another device. That'll show a short code they can enter on the original device to actually log in. It's not perfect, but it works.
I do fully agree that passwords should always be an option as well.
I don't like this kind of smoothing at all. It feels slow to me. Please just toggle without animations instead. And yes, I know these examples have been slowed down.
And auto vectorization isn't all that common. In many cases you need to structure your code in a certain way, in which case you're better off doing it yourself if you want the vectorization benefit.
What would change that to 'very happy' in your use case?
