Bitcoiners who like to take their self custody seriously often use tools like fire resistant metal plates to write their recovery seed words through a center punch tool. Products like the coinkite seed plates backup exist but it is also possible to roll your own using washers and bolts. For BIP39 only the first 4 letters of each word are necessary. You can also setup multisig or seed x0r to make sure a thief doesn’t breach into your seeds with just one plate, often stored on multiple geographic locations.

I wonder if some similar strategy exists for normal master passwords. Could be a nice idea for a low-tech-product-for-high-tech-solutions product. Perhaps a metal card where the user can manually punch a QR code.
