Unable to send emails from google account

Goodday, I am unable to send emails from manager. Error message is “The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required. Learn more at”"

All parameters have been accurately inputed and still getting error message…

Read this Guide: https://www.manager.io/guides/9100. Follow all relevant links in the Guide. If you still cannot resolve the problem, furnish all the information requested by the Guide. Show a screen shot of your Email Settings page, not a transcription. Obscure only proprietary information.

you should be including more information like, what version of manager you are using, what environment etc. But as @tut said, make sure you’ve read the guides and post more pertinent info for people to help you.

This looks like it’s going to be a 2FA or Google Apps Authentication issue. What have you done further to diagnose your problem?

Log in to your Gmail account through a web browser and enable access through less secure apps . Less secure apps can make your account more vulnerable, Google will automatically turn this setting off if it’s not being used. However, bypass this security setting with a configuration tweak within your Google Email Account .

To do so, first head over to https://accounts.google.com/ → Security → Enable Less Secure Apps

Enabling access for “less secure apps” means that the client/app doesn’t use OAuth 2.0 . OAuth 2.0 is the industry-standard protocol for authorization. When you sign in with OAuth 2.0, you sign in to Google’s system directly. In OAuth 2.0 , you authenticate directly to Gmail with your credentials and authorize an app to do certain things. The third-party app only sees an authorization token provided by Google as proof that you authenticated correctly and agreed to authorize that app.

Dear @ronaldgevern welcome to the forum.

You’re responding to a two year-old post that has since been answered in post #2.
