You don't need their password to send email. You need password to your stmp server . You have to sing in to it to send any mail. Try to create an email address for test puproses and use it credentials to send email.

There is part which you should fix for gmail stmp server:

smtp.Host = "smtp.gmail.com";
stmp.Port = 465;
stmp.EnableSsl = true;
smtp.Credentials = new System.Net.NetworkCredential
             ("example@gmail.com", "exampleGmailPassword");
