How can I enter the account and password required for launching an app?

You can enter your app test account and password. You can customize a virtual account in email address format and select America as the registration area. When you register the account, contact Tuya personnel to obtain the verification code. Bind a device to the account for testing, which can be a virtual device. Ensure that the device is online in the review period and the same as that in the screenshots and demonstration video.
