Thanks to [this answer](https://unix.stackexchange.com/a/587691){target="_blank" rel="noreferrer"} on Stack Exchange for the fix. + +The reason I needed this fix was because `pinentry` would pop up quite regularly when running `ssh`. I had the `default-cache-ttl` and `max-cache-ttl` values in ~/.gnupg/gpg-agent.conf so that GPG would cache my passphrase for an entire day but that didn't appear to be applied to SSH. I read through the man pages didn't find anything to help. I am sure I am missing something, hopefully in the next week or two I can figure it out. + +In the meantime, my updated setup is much smoother now that I don't have to go hunting for `pinentry`.
