I transfer the database, keyfile, and exe files to the new target, then login. Or I might just hand-type the random-string, viewed from my phone, because I am a hardcore operations administrator. In the event of a catastrophic loss of access, I retain backup codes physically recorded in a safe location. And the keyfile, database, & exe are currently in 3 separate devices of mine.
All 3 PCs are in one location, as I only have one living location and rent no colo or VMs. But I'm not worried about having some sort of Dropbox access issue at the same time as a physical incident at my residence, as the probability is (I think) still lower than my very low risk avoidance.
