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 (300-1) and second authentication information corresponding to a second domain associated with a second security access point (300-1), the method comprising: receiving a signal from an security access point (300-1) 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 (300-1); transferring (S501) the selected authentication information to the security access point (300-1), through NFC, to release a locked state of the security access point (300-1) to enable the mobile device to access a domain associated with the security access point (300-1); and displaying a graphical user interface for controlling a plurality of controlled devices corresponding to the domain associated with the security access point (300-1), 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 (300-1) corresponds to the first security access point (300-1) or the second security access point (300-1); selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point (300-1); and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point (300-1) receiving a signal from an security access point (300-1) 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 (300-1); transferring (S501) the selected authentication information to the security access point (300-1), through NFC, to release a locked state of the security access point (300-1) to enable the mobile device to access a domain associated with the security access point (300-1); and displaying a graphical user interface for controlling a plurality of controlled devices corresponding to the domain associated with the security access point (300-1), 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 (300-1) corresponds to the first security access point (300-1) or the second security access point (300-1); selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point (300-1); and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point (300-1) determining whether the security access point (300-1) corresponds to the first security access point (300-1) or the second security access point (300-1); selecting the first authentication information if it is determined the security access point (300-n) corresponds to the first security access point (300-1); and selecting the second authentication information if it is determined the security access point (300-n) corresponds to the second security access point (300-1) <EOS>
