其找回密码的流程如下：

第一步：输入用户名，系统查找是否存在该用户，如果存在则进行下一步，并给出用户的邮箱；否则提示"不存在该用户"

第二步：存在该用户后，则进行用户的邮箱验证，每个用户绑定一个QQ邮箱，点击"发送验证码"按钮，系统会给该邮箱发送一条包含验证码的邮件，发送成功，系统会在前端显示"验证码已经发送到你的邮箱，请查看"。用户填入该验证码，并且两者相匹配，则可以进行下一步，否则无法进行下一步，会提示"输入的邮箱验证码错误"

第三步：查看邮箱收到的邮件，复制验证码，填入系统第二步框中，进行第三步验证。通过前两步的验证，已经可以验证，操作者就是本人，所以第三步，用户可以直接修改密码，覆盖原密码

第四步：成功找回密码，是一个新的密码，用户可以返回登录页面进行登录
