Perhaps you could also print an encrypted version of your Bitwarden TOTP secret on a QR code and bring it with you in your luggage?
So, encrypt the secret with a passphrase you can remember, encode the entire thing in a QR code and print it on a piece of paper. Easy.
In Denmark we have a saying: “When there’s two Thursdays in a week”, which is used when someone asks you something like “when can we have this thing?” or “when will you do that thing?” or “when will you give me a million dollars?”
So, Thursday.
