One issue: where/how to store the backup codes? Paper in a box in the bank? Not very convenient if you are traveling and lose your primary device. Paper in your wallet? Not very secure (and the probabilities of losing your wallet and losing your phone are correlated). Encrypted file on dropbox? I don't trust myself not to make a stupid mistake and leave an unencrypted copy in a "temporary" file somewhere.
TOTP key: load it onto 3 password-protected Y4 keys. Take two of them with you on your trip, and leave one in the bank. No way (without very expensive expertise) to extract the TOTP keys from the Y4, which also means that a user blunder won't expose the keys, and hopefully your Y4 password is strong enough to give you time to change the TOTP keys before anyone cracks a lost Y4.
