I keep paper copies of the backup 2FA codes for Google and LastPass in my wallet and have been pretty happy with that strategy. A couple of years ago, I had my wallet fall out of my pocket while I was on a boat. My phone was back at the dock safe and dry so I had my primary authenticator. And I probably had printed copies somewhere at home. I've been much more diligent since then about making sure there are copies and that they're accessible.
