A universal access method performed by a mobile device that stores first authentication information corresponding to a first domain associated with a first security access point and second authentication information corresponding to a second domain associated with a second security access point, the method comprising: receiving a signal from an security access point that requests authentication information from the mobile device through near field communication, NFC; selecting one of the first authentication information and the second authentication information corresponding to the security access point; transferring the selected authentication information to the security access point, through NFC, to release a locked state of the security access point to enable the mobile device to access a domain associated with the security access point; and displaying a graphical user interface for controlling a plurality of controlled devices corresponding to the domain associated with the security access point, wherein the graphical user interface is configured based on setting information associated with the plurality of controlled devices and a user of the mobile device; wherein the first domain includes a first plurality of controlled devices (300-n), and the second domain includes a second plurality of controlled devices (300-n); and wherein the selecting comprises: determining whether the security access point corresponds to the first security access point or the second security access point; selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point; and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point receiving a signal from an security access point that requests authentication information from the mobile device through near field communication, NFC; selecting one of the first authentication information and the second authentication information corresponding to the security access point; transferring the selected authentication information to the security access point, through NFC, to release a locked state of the security access point to enable the mobile device to access a domain associated with the security access point; and displaying a graphical user interface for controlling a plurality of controlled devices corresponding to the domain associated with the security access point, wherein the graphical user interface is configured based on setting information associated with the plurality of controlled devices and a user of the mobile device; wherein the first domain includes a first plurality of controlled devices (300-n), and the second domain includes a second plurality of controlled devices (300-n); and wherein the selecting comprises: determining whether the security access point corresponds to the first security access point or the second security access point; selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point; and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point determining whether the security access point corresponds to the first security access point or the second security access point; selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point; and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point
