GWM400 SMS to Email

I have setup VS-GWM400 with SMS to Email using a Gmail account.
for it to work, I had to turn on "access for less secure apps" settings. Now google has disabled the access for less secure apps.
How do I correct this? Is there a firmware update to fix the issue and support Gmail?

What's the supported or required SMTP version ? to have the SMS to EMAIL work?

Thanks.
