Disable Two Factor Authentication without the SMS access?

I need to login to Unity but 2FA disallow be to do so, because I’m currently in overseas and don’t have access to SMS.

I can login to Unity ID website but I cannot change mobile number, or disable 2FA…

I need the “recovery code” to do so but I couldn’t find it.

I have access to the email account, is there anything I can do?

For Windows logon, the 2FA process can be implemented using Windows Authentication Framework (WAF), which is a feature of the Windows operating system. After entering the username and password, the user is prompted to enter the OTP or scan their biometric information. The OTP can be sent to the user’s mobile phone or to a hardware token. If the authentication is successful, the user is granted access to the system
