Email Authorization Code Help
What is an Authorization Code?
An authorization code is a dedicated password used for third-party email client login, replacing traditional email passwords. To protect your account security, QQ Mail and 163 Mail require the use of authorization codes for SMTP/IMAP login instead of directly using your email password.
Important Note:：Authorization codes are different from login passwords, please do not confuse them. Once an authorization code is generated, please keep it safe and do not disclose it to others.
