Hi MU Friends,
We improved the In-Game's Security System with Two-Factor Authentication.
When we activated Two-Factor Authentication, we will login Game with 6-digits TOTP on your Authenticator device (e.g. Google Authenticator) instead of usual password.
Ideally we should use usual password and TOTP code as Two-Factor Authentication for In-Game's login.
But in order to simplify the login process, we will use only TOTP code for now.
Note: Website's login process still uses usual password and TOTP code as Two-Factor Authentication which slightly difference with In-Game's login process.
Let's give a try and enjoy!
