in addition to the SSH agent and 1Password CLI introduced in 1Password/YouTube/Dev Tools Walkthrough, this shows 1Password/Dev/Watchtower which helps review SSH activity
Person/Floris van der Grinten provides a competent overview of how to use 1Password/Dev/op CLI tool to be an ssh/agent as well as how to use it to inject secret references using a Biometric unlock that persists in a shell session.
After watching this video I had more confidence that Biometrics could be used to get secrets off of disk in all the "normal" cases, but I still have questions about how this interacts with local VMs and Docker.
