When you forget the password of the graduate education management system of Henan University, you can try the following steps to solve the problem. First of all, when visiting the login page of the system, there is usually an option to forget the password or retrieve it. Click this option, the system will ask you to provide some personal information to verify your identity, such as the email address or mobile phone number you used when registering. After the verification is completed, the system will send you an email or SMS with a password reset link or a temporary password. You can reset the new password by clicking the link or using a temporary password. If the password retrieval function can't solve the problem, I suggest you contact the relevant departments of the graduate education management system of Henan University, such as the Academic Affairs Office or the Information Technology Department, to explain the situation to them and ask for help. They will be able to provide specific guidance and support to help you restore access to the system.
