i very much agree.
i am scared "to death" (maybe not that much, but...) ...of ever losing my phone, because all my stuff is coupled to it.

now imagine:
1. a simple phrase memorized by me, could be put into any device anywhere (even temporarily) to get access to all my data & apps temporarily and then deleting it again.

...if i lose my phone, i could grt a new device or even borrow someones to help me out.

tech coupd do it, but current tech and vendor lock ins prevent it.
