The problem when Chinese user enabling GitHub two-factor authentication via SMS
今天发现 GitHub 有两步验证的功能,于是打算开启,可是悲剧的是,到了填写手机号的时候,发现没有 China 的选项。
于是我尝试了下修改网页源代码,添加了 `<option value="+86">China +86</option>` 再填手机号,居然就收到短信了。
后来有点不放心,还是给 发了个反馈,然后收到回信说由于某些国家的短信发送成功率无法保证,所以没有开启两步验证功能。
大家如果也需要开启两步验证,最好把 Recover code 也记下来吧,避免以后短信收不到。

I found that the country code field has no option for Chinese users when I was enabling two-factor authentication via SMS:
<select class="js-country-code-select js-2fa-confirm" autocomplete="tel-country-code" name="countrycode">
<option value="+257">Burundi +257</option>
<option value="+855">Cambodia +855</option>
<option value="+1">Canada +1</option>
<option value="+238">Cape Verde +238</option>
<option value="+1345">Cayman Islands +1345</option>
<option value="+61">Christmas Island +61</option>
<option value="+61">Cocos +61</option>
<option value="+243">Congo, Dem Rep +243</option>
<option value="+385">Croatia +385</option>
<option value="+357">Cyprus +357</option>
<option value="+420">Czech Republic +420</option>
<option value="+45">Denmark +45</option>
I am wondering if this is a bug?
BTW, I have fixed the problem by adding `<option value="+86">China +86</option>`, and it works because I have received the message from GitHub!

Hi Xcat,
Due to the importance of two factor authentication messages we want to be extremely confident in the delivery rates before we enable one time password delivery via SMS since heavy delays render the one time password useless and being unable to receive one prevents you from accessing your account.
This is the reason that SMS is not presented as an option in some countries. As our provider advises us on the delivery status in specific countries we'll revise the list:

添加了 <option value="+86">China +86</option>

We tried delivering an SMS to that number, but the number doesn't seem to be valid.
