If you can’t, then just buy another Trezor and restore the wallet. I’m not sure, but I wouldn’t trust putting the seed phrase to your savings into your phone keyboard.

It’s up to you and your risk profile on whether you do this, because it would turn what is likely a cold wallet into a hot wallet (less secure, will be quickly swept if you have a virus)

But the answer is yes. That pin probably just unlocks the UI of the device so it can sign transactions.

If you recover to blue wallet, you won’t need the pin.
