I keep 3 keys active. One is on my keychain, one lives in a locked file cabinet in my home and I have one at my parents house on the other side of the country. I primarily use them for u2f and totp, though I want to deep dive into ssh via OpenPgp one of these days. When I want to add a new site, I: 1. Set it up on my keychain key. 2. If at home, set it up on my backup. If not, print out the totp secret on paper and when I get home, add it. 3. Call my parents and ask them to plug the 3rd key into a windows box I can Remote Desktop into and set up either totp or u2f via Remote Desktop. Once done, I ask them to unplug it (it’s attached to the desktop pc case with a lanyard). I find the “key at parents house” to be really helpful, as if I’m traveling and lose/destroy my keys, I can just call them and ask them to plug it in and then I’m back in business.
