Why does the authentication failed error occur and how do I resolve it?

You will receive this error if you have enabled two-factor authentication for the email that you want to configure. In that case, instead of using the email password, use the App-specific password. This should resolve the issue.

For example, in case you have a Gmail account, here is how you generate an app password.
