When users download the APP for the first time on a new device, they can register an account to log in or use guest login;
Register account login
By creating an account and password to register an account, the account is permanently locked to ensure absolute security. It is recommended to go to the login page to create an account and password to register when entering the app for the first time;
Guest login
Guest login cannot be logged out. A device has only one ID number. In principle, the ID will not change, and the time will not change. However, in extreme cases, the device ID may change due to uninstallation and reinstallation, upgrading the mobile phone system, resetting the mobile phone system, etc., which will cause the guest account to change and cannot be retrieved. Therefore, it is recommended to register an account as soon as possible. After binding, the time in the guest account will be transferred to the account.
