Engrave your secret key on a sheet of metal, then store that in a bank deposit box. Add a note for your heirs. Include the contents of the box in the will.
Government bureaucrats are known to violate privacy and confiscating or arresting the contents of safety deposit boxes for political and other illegitimate reasons.
Creditors, past spouses, tax authorities, frivolous lawsuits, courts, political opponents - when powerful enough can tap into your safety deposit box.
Imagine the jackpot they’ll hit finding the magic words.
Yet people keep suggesting safety deposit boxes as a great solution.
Thanks for responding. I understand it's all about threat modelling but would this necessarily be too much of an issue for a government to gain access to? The will would still describe how to bring all the information together.
The government doesn't necessarily need to know the location of each piece.
Of course bank safety deposit box is an easy target, but it's easy to spread more pieces among lawyers, family, even friends, even without them knowing what it is.
