All your crypto (actually the keys of all those crypto addresses) are on your trezor nowhere else. Yoroi is just an interface that exports the keys from your trezor and shows your ada and allows an interface to create transactions. but all has to be always signed by your trezor.
I see.
So my trezor is fine, just the hidden ada wallet i created has a passprhase one.
So unless I rememeber it, I think its gone!
I am not 100% sure about this since I don’t use a passphrase on my trezor, so somebody else correct me if this is wrong. But what I think is this:
A passphrase cannot be bypassed. even with your seed since it’s part of the seed. Actually each passphrase will give you access to another wallet. The idea of the passphrase is that you can have 1 hw wallet and 2 passphrases. put most of your crypto under a passphrase and just a bit under the “blank” passphrase. This gives you added security. this is also explained by the trezor blog I linked above.
