GitHub开启二次验证后会导致博客提交的时候密码错误，无法提交至GitHub。具体提示如下：

这是由于在GitHub中开启了 Two-factor authentication（二次验证）导致。

两种解决办法：

一、关闭二次验证

不建议使用该方法，因为开启二次验证虽然在某些时候增加了一些麻烦，但是极大的提高了账户的安全性，我觉得这是值得的。
关闭步骤：

  1. 登录github.com
  2. Settings->Security
  3. 在 Two-factor authentication 栏下点击Edit
  4. 点击 Disable two-factor authentication

关闭二次验证后，hexo部署提交时使用的密码即为GitHub网站用户密码。

二、生成 Personal access tokens 令牌码，使用该码作为密码登录

生成步骤：

  1. 登录github.com
  2. Settings->Personal access tokens->Generate new token
  3. 给新令牌添加好备注
  4. 勾选该令牌权限，如图
    来自GitHub官方帮助文档
  5. 点击 Generate token 生成令牌码
  6. 保存好生成的令牌码，该码即为
    1
    hexo d

后提示输入密码时使用的密码

为了安全起见，建议不要关闭二次验证。使用安全的令牌码进行登录提交。
