I don’t use 2-factor authentication as far as I can see in my Gmail account settings.
I have retried on another network (outside the network of the company) and the problem persists. I have also tried two different encryption methods TLS on port 587 and SSL on port 465.
When I try to send the mail when configuring the email connector, it keeps throwing an error.
Could you please provide me some more information so that I can try again (with some screenshots)?
That’s exactly the input I have inserted when I tested the connection.
Could it be that you need a special type of Gmail account for this or tweak some settings in Gmail itself? I am using a free Gmail account for testing.
Enabling access for "less secure apps" means that the client/app doesn't use OAuth 2.0 . OAuth 2.0 is the industry-standard protocol for authorization. When you sign in with OAuth 2.0, you sign in to Google's system directly. In OAuth 2.0 , you authenticate directly to Gmail with your credentials and authorize an app to do certain things. The third-party app only sees an authorization token provided by Google as proof that you authenticated correctly and agreed to authorize that app.
