Googlemail blocks VeraAlerts

Hi @,
I’m not able to use VeraAlerts with Googlemail. It seems that Googlemail blocks the VeraAlerts’ login because I receive a mail with subject “Sign-In attempt blocked”. Is there a way to allow VeraAlerts-login in Googlemail?

You have a bad password … or you have two factor authentication and have not used the “specially generated password” for use by servers that access an account with two factor authentications.
