[Custom SMTP Email Server] - Google SMTP - 534-5.7.9 Application-specific password required
[Custom SMTP Email Server] - Google SMTP - 534-5.7.9 Application-specific password required When using GoogleSMTP with Sisense, you might encounter an issue where emails stop being received, and the logs display the following error message: 534-5.7.9 Application-specific password required. This occurs because, if you have enabled 2-factor authentication on your Google account, you cannot use your regular password for programmatic access to Gmail. Instead, you need to generate an app-specific password to use in place of your actual password. An app password is a 16-digit code that allows a less secure app or device to access your Google Account. These passwords are only applicable to accounts with 2-Step Verification enabled. Steps: Log in to your Google account. Navigate to My Account > Sign-in & Security > App Passwords (you may need to sign in again to confirm your identity). Scroll down to the "Select App" section (within the Password & sign-in method box) and choose "Other (custom name)". Name the app password, for example, "nodemailer". Click "Generate". Copy the generated password and paste it into your Node.js script in place of your actual Gmail password.

If you're using Outlook365 as your SMTP server in 2024, you might encounter errors like "535 5.7.139 Authentication unsuccessful." Microsoft has disabled Basic Authentication and SMTP AUTH for security reasons. Sisense currently doesn't support Modern Authentication (OAuth), so reverting to Legacy Authentication is necessary for continued use. Learn more about these changes and how to adapt.
