You need to allow less secure apps, you can do it by click below link
https://www.google.com/settings/security/lesssecureapps
also try this one
https://accounts.google.com/DisplayUnlockCaptcha
if still not works try changing password for gmail

You need to set the Allow less secure apps: ON, login to google using the account desired, and go to the security page and set the Allow less secure apps to be ON.
