Yeah that’s right. You cannot use a Google account with Advanced Protection turned on to log into myViewBoard.
Googles Advanced Protection blocks third-party apps such as myViewBoard. Only Google apps and very few other third-party apps can access your Google account. Unfortunately, there is no way to whitelist myViewBoard.
So, what you can do is:
- Turn off Advanced Protection, or
- Lower down the security level from Advanced Protection to 2-Step-Verification.
- Use your email address to sign in.
Thanks and best regards,
