I haven't logged in for too long. Do I need mobile phone authentication?

If you don't log in for a long time, you need a mobile phone verification code to log in again, and not only the verification code, but also face recognition. Together, you can only log in if you have the same identity. If you play every day, you don't need a verification code, just do face recognition. The need for a verification code is generally due to doubts about identity.
