There isn't really any reason to have a backup 2FA key. Just have TOTP set up on each account as a backup, so that way if you lose your 2FA key you can still log in that way. Then just order a new one. But having an extra 2FA key just sitting in your drawer on the off chance you leave your laptop in a taxi or whatever isn't really necessary. Right now it's only major sites that support U2F anyway, so basically all of them allow you to have TOTP enabled as a backup. If you want you don't even need to enter the TOTP codes in your phone, you can just store the secret keys encrypted somewhere.
