So I do actually use a safety deposit box at the bank he mentions - and I think it is worth the £20 a month. It does contain a backup yubikey (which is set as a master for creating new ones) as well as a printed paper copy of my private key. The 2nd slot on it stores the secret key for my 1password so I can get back into that if needed. I use Authy for 2FA which is backed up with a decent password that I know - but would be pretty tricky to guess. The bank have a photo of myself and wife, along with signatures - so when you go to access it they compare your photo (I had to show ID last time as I had grown a beard which looked nothing like me) and have you sign to access. So I think even if I had lost my card with my account details on it, I should still be able to get back into my digital life. Edit: Even if the safety deposit key is destroyed, you can get a replacement for <insert fairly high amount of money> if it came to it.
