Missing credentials for “PLAIN” nodemailer

Question

I\'m trying to use nodemailer in my contact form to receive feedback and send them directly to an email. This is the form below.

Answer 1

Gmail / Google app email service requires OAuth2 for authentication. PLAIN text password will require disabling security features manually on the google account.

To use OAuth2 in Nodemailer, refer: https://nodemailer.com/smtp/oauth2/

Sample code:

var email_smtp = nodemailer.createTransport({      
  host: "smtp.gmail.com",
  auth: {
    type: "OAuth2",
    user: "youremail@gmail.com",
    clientId: "CLIENT_ID_HERE",
    clientSecret: "CLIENT_SECRET_HERE",
    refreshToken: "REFRESH_TOKEN_HERE"                              
  }
});

And if you still want to use just plain text password, disable secure login on your google account and use as follows:

var email_smtp = nodemailer.createTransport({      
  host: "smtp.gmail.com",
  auth: {
    type: "login", // default
    user: "youremail@gmail.com",
    pass: "PASSWORD_HERE"
  }
});
