Authentication failed. Check the code for authentication

Authentication failed. Check the authentication code where the code is ... I can't understand the code completely. Hey

$mail->username = "963529987@qq.com"; Post Office User name (please fill in the full email address)
$mail->password = "***********"; Post Office password
Under these two checks, the verification failed-the account number or password is wrong

To new registration 163 mailbox try, QQ mailbox seems to have restrictions

$mail->username = "963529987@qq.com"; Post Office User name (please fill in the full email address)
$mail->password = "***********"; Post Office password
Under these two checks, the verification failed-the account number or password is wrong

I wrote the code. I don't understand. What is the Post Office user name not the email address of the sender?
