Don’t make it complicated…the problem here is if the metal plate is the only record of your private key then no matter how many signatures you have you’ve lost access to your #bitcoin
Always have physical, difficult to destroy backups in different locations. Pass phrase or have your own method for accessing the information.
Signatures? You only need 2 of 3 keys to access your money. So if you lost one in a fire or if a looter steals it, you can still get your bitcoin with the other two keys.
Agreed—I am thinking of single sig with backups. A multi-signature setup with geographical distribution is an extra layer of security, as would be single signature with geographical distribution and a pass phrase.
There are many ways to skin the #cat
Yeah the passphrase can work but then you need additional backups for the passphrase lol it can get complex
