If my Gmail account has Access for less secure apps disabled, then my application can't send emails through this account. Instead I get "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required" exception.
Here Google explains that by disabling Access for less secure apps, only apps that use modern security standards can sign in.
What are those modern security standards my code needs to implement and can you show me how to implement them with an example ( not sure if it matters, but my app and Gmail account aren't using 2-step verification )?
Here's the code I'm currently using:
public class EmailService : IIdentityMessageService
{
public Task SendAsync(IdentityMessage message)
{
var credentialUserName = "myAccount@gmail.com";
var sentFrom = "myAccount@gmail.com";
var pwd = "myPwd";
System.Net.Mail.SmtpClient client =
new System.Net.Mail.SmtpClient("smtp.gmail.com");
client.Port = 587;
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
System.Net.NetworkCredential credentials =
new System.Net.NetworkCredential(credentialUserName, pwd);
client.EnableSsl = true;
client.Credentials = credentials;
var mail =
new System.Net.Mail.MailMessage(sentFrom, message.Destination);
mail.Subject = message.Subject;
mail.Body = message.Body;
return client.SendMailAsync(mail);
}
}
