When logging into GitHub from an extension, we end up with:

The main CTA in the web appears to be Cancel.

We have 3 flow options:

• Auto-redirect back to VS Code (which may be the nicest, but it does have the above confirmation)
• Redirecting to a localhost server which doesn't bring you back to VS Code but lands you on a page that says something to the effect of "you can close this tab"
• The device code flow

We could run an experiment to make the redirect to local host the default and compare the drop off rate to the auto-redirect.

We could look to still use the protocol link to open VS Code from that localhost page, so we would get the best of 2 worlds:

• sign-in completes in all cases and will never hang
• we can still bring VS Code to the front via protocol link
