The passphrase is like a 25th word of the seed. Every passphrase gives you a different wallet, and if you forget the passphrase (or lose the seed) the BTC stored in the wallet are lost.
So
johoe, Where do I put the passphrase when recovering? It's much longer than the BIP44 words, so It cannot be in the seed.
You do not use the passphrase when recovering only when accessing the wallet. You can also recover the Trezor seed to Mycelium wallet on Android.
