Can a Live Share guest use GitHub Copilot in Visual Studio Code?

Question

During a Visual Studio Code Live Share session, the host (who initiated the live share session) can use GitHub Copilot as normal. The only caveat seems to be that the guest doesn't see Copilot suggestions until the host accepts them.

But can a VS Code Live Share guest use GitHub Copilot as well?

And if so, who needs to be logged into their GitHub account (with an active Copilot subscription) in order for the guest to use Copilot -- the host or the guest?

I'm interested in both:

• The conversational copilot features (e.g. in the right sidebar or in the inline chat widget).
• The inline completion functionality.

Answer 1

Just enabling Copilot globally isn’t enough.
When you join a Live Share session, VS Code runs a second extension host for the shared workspace, where extensions start disabled.
• Open Extensions ➜ search GitHub Copilot ➜ click the ⚙️ gear and choose Enable (Workspace) (or Install in Workspace).
• Reload when prompted and sign in.

Each guest needs their own Copilot subscription; once the extension is enabled in the workspace, both inline completions and Copilot Chat work normally.
