How to Bypass Missing China Option and Enable GitHub 2FA Easily

Recently, GitHub shows a yellow prompt asking to enable two‑factor authentication (2FA). The user tried to remove it but the country selection list does not include China, making the process impossible.

Some users share a JavaScript snippet that manually adds a “China +86” option to the dropdown:

var option = new Option("China +86","+86");
option.selected = true;
document.getElementById('countrycode').options.add(option, 0);

However, this method no longer works for receiving the verification SMS.

Ultimately, the verification was completed using an authentication app. Click the link at the bottom of the page to open the QR code, then scan it with an app such as 1Password, Authy, or Microsoft Authenticator.

After scanning, the app generates a one‑time password that can be entered into the input field at the bottom of the page to finish enabling 2FA.
