Buddy your right and I think if he had eventually tried this act then his bitcoin phrase has been compromised. I would recommend he start over with a brand new seed and send his bitcoin over there if he really cares about his portfolio or passing it to his next generation. These mistakes are exactly how fraudsters steal bitcoin. Then are left with nothing and no idea how it happened, blaming their wife for their own mistakes because they didn't take this seriously.

Maybe if he uses the Trezor wallet, he can use a unique feature called the "advanced recovery phrase." This lets him add his own secret words to his recovery phrase. This means he can keep his recovery code even safer. Even if someone finds it, they can't get to his coins because they won't know his special words.
