1, Open the Unity project via VCC.

2, Try to log in to SDK.

3, Asked to enter the two-factor authentication code.

4，Input the two-factor authentication code sent to my registered address and press "verify" button.

5，"Invalid Code" is displayed and I can not log in to my account.

I have been getting the same bug no matter how many times I repeat the process.

My friend is also suffering from the same bug.
