I am trying to setup scan to email using my gmail and it keeps telling me invalid username and password. I know my login is correct and i am using the smtp of smtp.gmail.com and port 465. Why isnt it working. I am also using MacOs High Sierra.
Within the Sign-in & security section click on Signing in to Google and ensure that "2-Step Verification" is set as "Off".
Within the left pane click on Connected apps & sites and ensure that "Access for less secure apps" is set as "ON", otherwise the verification will fail.
Within the left pane click on Device activity & notifications, witin the 'Recent security events' section click the Review events link and ensure there are no blocked connection attempt (it will be highlighted in red) , if there is any alert follow the steps on screen to ensure there is no block for that device.
Once you are done run a test for the outgoing user profile and check if the problem been resolved.
