alt Hacker NewsI've been using Secretive (a nice software wrapper for these) for a few days for my Github keys (where 1Password holds the rest of my SSH keys). It works nicely, but obviously you can't back up a key that started life in a secure enclave, so you'll need alternative access arrangements for anything you setup that way.
2nd this. Found out about it when this type of thing came up about a week ago. I had a hard time getting the stock stuff going but Secretive made it easy to set up and I love using it.
Definitely a recco from me as well. -- git hub here: https://github.com/maxgoedjen/secretive
