Resolved! I hope this helps others in the future.. Even though I enabled gmail "access to less secure apps" it kept rejecting the PHPmailer sign in.. Seems that for some reason gmail wasn't accepting port 587, at least for me, so I switched it to 465 and everything started working right a way.

As a plus for this answer, as for what @Amit Merchant suggested in the comment section, I wasn't aware of what the last comment in stackoverflow.com/a/33667250/1485183 says, it basically shows a gmail feature I never found or heard when looking for a solution for my problem, that this: accounts.google.com/DisplayUnlockCaptcha

I'm sure this will help someone some day whether if it's for phpmailer or any other library.
