Furthermore, you have to install their entire app to use TOTP. Their app includes everything but the kitchen sink, and murders phone batteries even when in the background. On top of this, I don't see a point in installing apps if the functionality is also provided by their website. If I'm using my phone for 2FA, I'd like my phone to be secure, and I trust the security of my phone with just Chrome on it more than I trust my phone with Chrome and a million other apps.

this is the comment I was looking for. not only do they do this (which is not a good excuse), they also BEG you to put in your phone number every other day.

I've seen websites (I believe it was netflix) which ask for your phone number in order to provide you a way to reset your password... what happened to good old email resets?
