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 https://support.google.com/mail/answer/78754
Please note: 2-step Verification option will only be visible if your google administrator has it enabled for your organization.
To enable 2-Step Verification on the Google Account:
To enable App Passwords please follow the steps below:
An App password is a 16-digit passcode that gives an app or device permission to access your Google Account. More information about App Passwords can be found here: https://support.google.com/accounts/answer/185833
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.
Please note: This option will not be available if this has been turned off by your Google Administrator.
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.
