# How to login? **Member** does not have its own login system and relies on a third party account login system developed by the Institute of High Energy Physics for account registration and login. This means that **Member** does not keep your account password and you do not need to register a separate account for **Member**. If you are already an employee or student of IHEP or if you already have an account with IHEP, you can log in directly using that account. If you do not yet have an account, please click the [link](https://login.ihep.ac.cn/login) to register for an application. **Please note**: Member is not responsible for IHEP account and its password and if you have problems with your account, please contact n**.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
