I hope its OK for me to jump on this thread and share my inner most thoughts about these SE wallets.  If I am honest I don't know if I am willing to trust that these chips are perfectly SECURE as they contend.  Not going to pick on a specific mfg or chipset, just my general thinking.  I read about this stuff until my eyes bleed at times.

My contention here is that I effectively create my "own" SE Trezor by using SD Protect on my Trezor T's.  I know you will likely shrug this post off but to me its reassuring to know that my "T's" if I handed them all to you have 100% encrypted SEED and PIN masks!  There is no question at all that the SEED and PIN are unavailable to acquire.  Now to me that is SE in a way that lets me sleep well at night.  Sure I need to handle my microSD card but that is child's play for the autoscripts I use to wipe and write back the needed file when the time comes.  Seconds at most.



And like we all know further compounding wallet security with long and difficult passphrases in addition does mitigate the SE issue!
