Subject: [PATCH] feat(auth error): Subdivide the cause of the error and
determine whether to record the error according to the cause and mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- 细分错误原因，根据原因以及模式不同，判断是否记录错误，例如多路认证不存在认证设备或认证被取消的情况下将不记录内部错误次数以及外部faillock次数
