    • Embodiments of this application provide a cross-device authentication method and an apparatus. The method includes: A login authentication initiation device determines, from at least one electronic device, a login authentication device of a to-be-authenticated application, where an authentication application is installed on the login authentication device, and the authentication application is logged in; the login authentication initiation device sends a first login authentication request to the login authentication device; the login authentication device displays an account login interface of the authentication application based on the first login authentication request, where the account login interface includes a first button indicating to approve authorization and a second button indicating to reject authorization; the login authentication device obtains an operation instruction when a user performs a tapping operation on a first button or a second button; and the login authentication device feeds back a first login authentication response to the login authentication initiation device, where the first login authentication response includes indication information of a login authentication result. In this embodiment of this application, a complex process of installing and logging in to the authentication application on the login authentication initiation device can be avoided, thereby ensuring data security.
