Or, you could just write it on a piece of paper and give it to someone you trust.
...and then the person you trust misplaces that piece of paper, and it ends up in the hands of someone you DON'T trust. Your coins are gone!
My advice to anyone reading this:
DON'T share PINs, passphrases, seeds, anything of that nature, with ANYONE, not even your parents, children, spouse, etc. They may be the most trustworthy people in the world, but they may
carelessly compromise the security of your coins.
Perhaps, you
could share the seed with only one or two very special persons in your life, who fulfill all of the requirements below:
1. You fully trust them (obviously),
2. They understand what Bitcoin and the seed are, and are crypto-literate,
3. They take security matters VERY seriously,
4. Loved/family persons (parents, spouses, children) should be excluded if they don't satisfy 1~3, no matter how much you love them!
If persons belonging to (4) get mad at you for not sharing the seed with them, and complain that you don't love/trust them, etc., it means that they don't understand the implications of (2) and (3), and should never be given access to the seed.
IE. Give it to someone you trust.
