I have a kindle that I've had for ages. It has been jailbroken for a while and I've been loading my own epubs onto it. They make it easy with the 1 click send to kindle stuff but that locks you in to their ecosystem.

I've gotten it to "work" but it's fragile and updates tend to break it. I ended up switching to FreeCAD, it's come a long way and version 1.1 is pretty great.

Email is considered insecure as a 2nd factor. TOTP stands for Time-based One-Time Password. Usually you store a seed and that combined with the time generates a time based password. If someone intercepts it, it's only valid for a certain time frame (I think about a minute or so), after which it's invalid.
