Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Solution for advanced users: id_rsa on public site, strong passphrase = ability to re-establish auth roots from anywhere with new device.

          One important caveat: if you think passphrase may be compromised, you must delete pubkey from trust. Changing passphrase doesn't help.

          what would be the advantage over using the password directly?

          You can use the same key for multiple/all sites. Only one passphrase to remember.

          ah ok yeah true that's easier to manage. and then access a pw-manager via the key for other sites?

          Yeah. Of course ssh is just my preferred "auth root". An alternative for other users would be putting your encrypted pw-mgr file on pub site

          How about a set of S/KEY sequences on a small index card in your wallet? (I've never done that so I'm genuinely curious.)

          I used to use various otp schemes when travelling, but "something you know" is harder to lose than "something you have".

          And I trust math more than physical safety of wallet.

          Depends very much on your attack scenario. Private key files only have their kdf to defend them. Easy to parallelize brute force.

          Yes, you need a really strong passphrase.

          My problem is deciding between "something I'll forget" and "something I'll lose"
