What is your suggestion?

It would be nice to support SSH agent forwarding and the use-cases it enables.

At minimum this would be supported via ssh coder.[workspace] syntax but ideally also by coder ssh.

Why do you want this feature?

There are a few use-cases for this functionality:

• As a developer, I want to use my YubiKey to authenticate all interactions with my GitHub repos
• As a developer, I want to use the SSH keys generated in 1Password, together with the 1Password SSH agent to grant key access via biometric authentication
• As a developer, I want to sign my git commits using my YubiKey, smart card or locally stored GPG key

A few of the existing SSH agents are:

• SSH Agent (available on most platforms)
• yubikey-agent
• 1Password SSH agent
• GNUPG Agent with --enable-ssh-support

Are there any workarounds to get this functionality today?

A quick draft PR has been created #1548 that adds a basic building block to support this feature, but it's not user friendly (yet).
