I’m getting the error “The SMTP server requires a secure connection or the client was not authenticated…” while trying to send an email. How do I resolve this?

You are trying to send an email or validate your email, and getting the error, “Cannot send mail. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Please try again.”

This message typically appears if the email or password or both are incorrect. Please re-check them all.

This message can also appear if you use Gmail and Google is blocking the sign-in attempts due to Security Standards. In that case, you will need to generate App Password for your Gmail Account to validate the Email. Here’s how:

  • Click on the Google icon.
  • Then, click on “Manage your Google Account”.
  • Click on the “Security” tab.
  • Under the “Signing in to Google” section, make sure the 2-Step Verification is turned On. If it is not, then turn it on.

  • After turning on the 2-Step Verification, go back to the “Security” tab and click on “2-Step Verification”.

  • Enter your Google Account Password for Validation, if prompted, and click on “Next”.
  • In the “2-Step Verification” page, scroll down to the bottom and click on the “App Passwords” option.

  • Here, select “Other (Custom Name)” from the dropdown options.
  • Enter “Xorosoft” and click “Generate”.
  • A 16-digit App Password will be generated for your device. This password grants complete access to your Google Account.
  • Copy this Password and paste this into Xoro’s “Email Password” field on the Email Configuration Setup page.
  • Save the changes and Validate the Email.

**Please note that it is mandatory to enable 2-Step Verification to be able to use this feature.
