YubiKey iOS: Unlocking SSH Compatibility

As a security-conscious individual, I recently found myself on the hunt for a Yubikey SSH compatible app that would allow me to utilize my trusty Yubikey with my iOS device. Unfortunately, after scouring the Apple App Store and searching for terminal emulators compatible with Yubikeys for ssh commands, I came up empty-handed.

Undeterred, I decided to dig deeper and explore other options. After some digging, I stumbled upon a few workarounds that allowed me to use my Yubikey with my Mac OS system.

To get started, I needed to configure my gpg-connect-agent to interact with my Yubikey 5 NFC device. To do this, I added the following lines to my zshrc file:

`gpg-connect-agent 'scd serialno' 'learn -force' /bye`

`export SSH_AUTH_SOCK=$(gpgconf -list-dirs agent-ssh-socket)`

With these settings in place, I was able to use my Yubikey to authenticate into the server seamlessly. When logging into my server from Mac OS using ssh, I simply used gpg-agent and public key authentication, storing my private (gpg) key credentials on my Yubikey 5 NFC device in the gpg format.

The end result is a secure and convenient way to log into my server on from Mac using ssh, all thanks to my trusty Yubikey. While I may not have found an official app that supports Yubikey SSH compatibility for iOS, these workarounds allowed me to achieve my goal of using my Yubikey with my device.
