PSA: Hold your Bitcoins in a 3of3 multisig with backups for each seed in 3 separate safety deposit boxes, where 2 out of the 3 seeds are in each, where one box being corrupted doesn't affect you whatsoever.

If you can't do this, you should use a Bitkey, adding as many emergency contacts as you can, as well as maxing out the number of fingerprints you can add to the device itself.

For large stacks that affect net worth:

Keep the Bitkey in a safety deposit box.

Keep a smartphone with the app in a separate safety deposit box.
