163 What should I do if the client sends a risky prompt email?

Modify passwords, set security questions and bind mobile phones. 163 If the mailbox prompts that there is a security risk, it may be because the account has a remote login record, or the login password setting is too simple and the security factor is low, or it may be because the user has not bound the mobile phone number or set a security problem, so the system will prompt that there is a risk. After changing the password, setting secret protection questions and binding the mobile phone, the account will no longer have security risk tips.
