As the title above, I have created a project with simple log-in and registration. Inside the program, I have use System.Net.Mail.SmtpException to send the email verification to the user email. I have done created the email but when I click on create a new account, I met this problem as well.
System.Net.Mail.SmtpException: 'The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required
From the information I search, I found out someone say I need to make my email 2-step verification. I did it but the problem still there.

The code above is the controller class I created. The problem I found is there so that I didn't put any other design html code in here. The most weird part is even I met this problem, the data I register still can key-in into the database but this annoying problem still exist there. Anywhere, if anything I miss put, please inform me ya.. Thank you.
