user27578: I'm trying to figure out how to use a Trezor for my needs. I'd like to have different "layers" of security, so my plan is to use this setup (less secure on top):

Online wallet for every day usage (1%)
Trezor with passphrase A connected to online computer (19%)
Trezor with passphrase B connected to offline computer (80%)

My question is: does it make sense to separate layers 2 and 3 in online and offline computers? I'm assuming that the Trezor does not store the passphrase, so by using passphrase B only in a secure offline computer to sign transactions this layer is much more secure.
Thanks!

user38618: No, you can use your Trezor for your everyday use with a usual online computer (or even a computer that has malware). Connecting your Trezor to your computer oftenly doesn't mean it is not secure anymore / it is less secure.
