An application triggering method wherein the method comprises: acquiring an input password after a triggering operation via an application icon is detected, the application icon corresponding to an application including at least two instances; the at least two instances including an original instance and at least one other instance created according to the original instance; the at least one other instance having a part of functions of the original instance; and triggering a target instance of the application according to the input password, different triggering passwords being set for the at least two instances of the same application respectively and the target instance referring to an instance for which the triggering password is the same as the input password; wherein the at least one other instance shares function data of the application with the original instance; in a running process of the at least one other instance, the function data of the application is loaded into respective processes to realize functions of the application; the method further comprising: creating the at least one other instance according to the original instance of the application when multi-instance creation operation of the application is detected, an instance identifier of the original instance and an instance identifier of the at least one other instance being associated with the application icon; acquiring triggering password set by each account system in at least two account systems on a terminal; the terminal installing an operating system supporting multiple account systems to implement coexistence of multiple account systems on the terminal; different account systems corresponding to different running spaces, and each account system independently running based on its own running space; and determining the triggering password set by each account system as the triggering password for each of the at least two instances; each instance of the application corresponding to the triggering password of one account system. acquiring an input password after a triggering operation via an application icon is detected, the application icon corresponding to an application including at least two instances; the at least two instances including an original instance and at least one other instance created according to the original instance; the at least one other instance having a part of functions of the original instance; and triggering a target instance of the application according to the input password, different triggering passwords being set for the at least two instances of the same application respectively and the target instance referring to an instance for which the triggering password is the same as the input password; wherein the at least one other instance shares function data of the application with the original instance; in a running process of the at least one other instance, the function data of the application is loaded into respective processes to realize functions of the application; the method further comprising: creating the at least one other instance according to the original instance of the application when multi-instance creation operation of the application is detected, an instance identifier of the original instance and an instance identifier of the at least one other instance being associated with the application icon; acquiring triggering password set by each account system in at least two account systems on a terminal; the terminal installing an operating system supporting multiple account systems to implement coexistence of multiple account systems on the terminal; different account systems corresponding to different running spaces, and each account system independently running based on its own running space; and determining the triggering password set by each account system as the triggering password for each of the at least two instances; each instance of the application corresponding to the triggering password of one account system. creating the at least one other instance according to the original instance of the application when multi-instance creation operation of the application is detected, an instance identifier of the original instance and an instance identifier of the at least one other instance being associated with the application icon; acquiring triggering password set by each account system in at least two account systems on a terminal; the terminal installing an operating system supporting multiple account systems to implement coexistence of multiple account systems on the terminal; different account systems corresponding to different running spaces, and each account system independently running based on its own running space; and determining the triggering password set by each account system as the triggering password for each of the at least two instances; each instance of the application corresponding to the triggering password of one account system.
