通过QQ邮箱网页端登录密码无法设置在第三方客户端（如foxmail,outlook等），或手机端（手机邮件收发APP）上面，必须生成授权码方能设置成功。

The password for logging into the email through the QQ email web page cannot be set on third-party clients (such as Foxmail, Outlook, etc.) or mobile apps (such as mobile email sending and receiving apps). An authorization code must be generated to successfully set it.

1、登录QQ邮箱，点击：账号与安全

Login to QQ email, click on: Account and Security

2、安全设置，生成授权码，选择邮件收取时间

Security settings, generate authorization code, select email collection time

3、用邮箱密保手机进行短信验证

Verify SMS with secure email and mobile phone

4、系统会生成一个16位的授权码，点复制，将这个密码粘贴（或者手动输入，区分大小写）到客户端或者手机端密码处，点击关闭。

The system will generate a 16 digit authorization code, click copy, paste (or manually enter, case sensitive) this password into the client or mobile password field, and click close.

注意：
a. 生成的16位专用密码不要保存，不用记忆，不要泄露给任何人，需要的时候可以再生成
b. 网页上不要删除这个16位专用密码，删除后客户端/手机端上将无法使用，除非不在客户端/手机端上设置了，可以删除网页上的这个特殊密码。

a. The generated 16 digit dedicated password should not be saved, memorized, or leaked to anyone. It can be regenerated when needed

b. Do not delete this 16 digit special password on the webpage. After deletion, it will not be available on the client/mobile end unless it is not set on the client/mobile end. You can delete this special password on the webpage.
