英文:
Face ID is disabled
问题
Face ID在我的应用程序中。用户表示，如果应用程序长时间不使用，Face ID会被禁用约3天。输入密码后，Face ID会再次可用。在长时间不使用应用程序时，是否有任何苹果限制？谢谢。
英文:
I use biometric in my application. Users say that Face ID is disabled if the application is not used for about 3 days. After entering the password, the face ID becomes available again. Are there any Apple restrictions when not using the application for a long time? Thank you.

要使用Face ID，您必须在设备上设置密码。以下情况需要输入密码进行额外的安全验证：
- 设备刚刚开启或重新启动。
- 设备未解锁超过48小时。
- 密码在过去的六天半内未用于解锁设备，而Face ID在过去的4小时内未解锁设备。
- 设备接收到远程锁定命令。
- 进行五次无成功的面部匹配尝试后。
- 按住任何音量按钮和侧面按钮同时按住2秒后，启动关机/紧急SOS。
