Continue with GitHub now appears beside Apple, Google and LinkedIn on the website's sign-in and registration pages, and in the mobile app.
A GitHub account signs in to the Magpie account it is linked to, or to the account with the same email address as the GitHub account's verified primary address, which it is then linked to. If no account matches, a new account is created. Connect or unlink GitHub in Account settings on the website. GitHub sign-in is separate from the Issues GitHub connection.
