For the error: "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at", you would have got an Email(Account of the 'emailSender' in the code) of subject: "Review blocked sign-in attempt".

Open that email and click on 'Secure Your Account' where in you will be directed to page where you can turn OFF"Disable access for less secure apps". Doing this should fix your issue.

This happens when you try login from different time zone or IP Address Computer. sign in to gmail once with your credentials. They will ask for the confirmation, confirm it and log out.

Hopes it help..!!!
