What are the current best practices for setting up proofs of your online identity? I've seen people on Mastodon using https://keyoxide.org/ for that, is it the right thing to use, and should I use it with GPG keys?

Also what's the best practice for setting up the key/identity for multiple machines? Should I just copy the private key around, or there are better ways of doing that?
