The problem is that it is Android only. If it were desktop/Android at least it would be be nice (I like to have one device as backup)
You could always use an old phone stashed away somewhere, or even download an Android emulator on to your computer and install it on that.
Thanks, but I prefer to use authy, which just let me install anywhere without any turn arounds.
We really need more competition in this 2ffa software market
