Any help is appreciated thanks.
I also got the "Application-specific password required" error when attempting to use my gmail as my email server.
As I had 2nd factor turned on, I found that I needed to set a separate app-specific password. After discovering this existed, this is how I'd want to do it anyway, even without being forced to. That way, I don't have to put my password that I use day to day for google into the splunk settings.
You can set an app password via https://myaccount.google.com/apppasswords
