Do you guys have plans for you BTC if you accidentally got hit by a bus?

I'm accumulating BTC and I've reached a level where it's no longer a hobby side saving but a substantial part of our family savings. The problem is that my children are young and my wife will not in a million year fiddle with my binance account and passkeys (or self custody wallet, Base in my case), and I worry what will happen if I got hit by a bus. I would love ideas from you guys about how you're planning for this (if at all)
