Setup the Administrator Passwords & the Door Access Password as follow:
System Administration - This is the user name and password required to configure the system (such as setting up the IP address of the device), and to administrate the users' settings (such as adding and deleting users). The default name is admin, and the default password is 123.
User Administration - This is similar to the previous one, except that it cannot be used to configure the system. There is no default value.
Door Access Password - This is the quick-access password for the Quick Accessconfiguration. This is the common password that all the users use to open the door during the high-traffic period (such as during normal office hour), when high security is not necessary.
