Monit Service not Operate

[ariefisk8]

Hi.
I've been configuring Monit service to send email (gmail) to let me monitor the events of my firewall.
But i keep having an authentication error.

Error:

Mail: Mailserver response error -- 534-5.7.9 Application-specific password required.

SMTP: Mailserver response error -- 534 5.7.9 https://support.google.com/mail/?p=InvalidSecondFactor x10-20020a1709029a4a00b001d34796c1e9sm8836413plv.119

Some said i need just to enable "Less secure app access" in my Google Account settings but I can't find this in my email security setting. I think it had been deprecated.

Then I used the "App Password" to generate a password then replaced my email password with it. I followed the Google instruction for this. But I still it doesn't work at all.

Please help. Thank you!
