也许是电脑端最方便的两步验证方式了
写在开头:早先在浏览技术区的时候看到大佬发的两步验证代码,复制了使用至今。时至今日已搜寻不到当年大佬的作品,故我另开新帖帮助有需要的人。优点:没有复杂的注册邮箱、布置**等操作;以网页的方式轻松获取“两步验证一次性密码”如上图所示 展示页面仅三行重要信息: 1、你的密钥(在你开启两步验证时生成的唯一密钥诸如A1B2C3D4E5F6G7H8) 2、两步验证一次性密码 3、一次性密码倒计时“1”这里可以输入你的密钥,自动更新一次性密码;也可以在代码里输入你的密钥,省去每次输入密钥的麻烦具体实现起来操作很简单,共分为3步:1、打开记事本文档2、复制下面的代码——注意:可以将代码中“A1B2C3D4E5F6G7H8”这段改成你自己的密钥——在第14行- <!DOCTYPE html>

3、 将代码粘贴到记事本文档内,保存为html格式文件(需要注意的地方如图) , 将生成如下图这样的图标(文件名自己造) 接下来就是当你需要两步验证的时候,复制6位一次性密码填入即可 如果你觉得有用,还请不要吝啬点赞。 祝各位榴友假日愉快,生活安康!
