Same goes for every serious app which need to ID you. The app-based 2FA/MFA is becoming the standard for the web access. This is a need or pattern created by availability of a bad solution. Similar to how the cars created sprawling cities in the USA which prohibits you using your legs.
So, telling people to use website instead of app, is the same as telling them to walk to the corner shop instead of using a car. You can't walk to the many other essential places anymore, though.
You can escape from the car if you live a small village that has everything you need. But you can't escape from apps and internet if you need to feel that you exist in this world.
I wouldn’t care, except they require it for payments and in 2024 they auto-enrolled us in “paperless”. Fixable - by using the EHR systems configuration (needs a mobile app to access) back to mailed bills.
Major issue is though, I was sending their voluminous useless survey emails to spam, as they do not allow patients to unenroll their email address (it’s the primary key essentially), and their unsubscribe is essentially useless, and so I did not see repeated requests for payment.
This resulted in a $90 copay *going to collections*. Which of course sent me a paper bill, thankfully, and I got to it before it impacted our ability to access credit.
