Authentication Failed error when sending email notifications via Google
KB Home | Authentication Failed error when sending email notifications via Google
When using a Google based email account to send email notifications in PaperCut NG & MF, you may run into the following error message:
Error sending email: Authentication failed; nested exception is javax.mail.AuthenticationFailedException: 534-5.7.14
Please log in via your web browser and 534-5.7.14 then try again
If you cannot enable 2-Step Verification and create an App Password, then you could create a siloed email address with a super long, super secure password, that is only used for email notifications in with PaperCut NG & MF.
Turn on Allow less secure apps
The quick and easy (and not so secure) fix would be to turn on “Allow less secure apps” in your Google Account settings.
