QQ Mail uses an authorization code instead of an app password. Use the authorization code as the client password—it is not your QQ login password.

​
Get an authorization code

1

Enable IMAP/SMTP

Sign in to QQ Mail web → Settings → Account. Under POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV Service, enable IMAP/SMTP Service.
2

Generate the authorization code

Complete SMS verification as prompted. The system will provide a 16-character authorization code. Copy and save it immediately.

  • Username: Full QQ Mail address (e.g. 123456789@qq.com)
  • Password: Authorization code
Re-enabling IMAP/SMTP or changing security settings may invalidate the authorization code. Regenerate it in the web UI and update your client.
