GitHub OAuth

Configure GitHub login in rs-auth.

GitHub OAuth follows the same flow as Google, but user info handling differs slightly because email resolution may require a second request to GitHub's email endpoint.

Current support includes:

authorization redirect
callback handling
account creation/linking
session issuance
JSON mode and redirect mode

GitHub email resolution prefers the primary verified email returned by GitHub when the main user payload does not include one.
