Sending a patch with git-email and a gmail account

Hi, I tried to send a patch with git-email account following tutorials I found on the web. I got and error saying "Unable to initialize SMTP..." I saw that many others get this error. I tried many solutions, but the only thing that worked was by going the gmail account setting, to "Sign-in & security" and to set "Allow less secure apps: " to be on. see in the "Answers" section in: http://stackoverflow.com/questions/28038662/unable-to-initialize-smtp-proper... Did anyone encounter this issue ? My question is: is there another way ? I am not happy to set "Allow less secure apps:" to be on, as this makes the security of my email account less strong, so it seems. Regards, Kevin
