displaying, based on the account authorization capability, an account login interface of the authentication application, wherein the account login interface comprises a first button indicating to approve authorization and a second button indicating to reject the authorization;

obtaining an operation instruction that is based on a tapping operation of a user on the first button or the second button, wherein the operation instruction comprises a login authentication result; and

feeding back, to the login authentication initiation device, a first login authentication response comprising indication information of the login authentication result.

8 . The method of claim 7 , wherein before receiving the first login authentication request, the method further comprises:

receiving, from the login authentication initiation device, a query request comprising the identification information and the account login indication information; and

sending, to the login authentication initiation device, a query response comprising a device identifier in response to the login authentication initiation device having the account authorization capability.

9 . The method of claim 7 , wherein feeding back the first login authentication response comprises sending, to a login authentication platform, a second login authentication response to enable the login authentication platform to send, based on the second login authentication response, the first login authentication response to the login authentication initiation device.

10 . The method of claim 7 , wherein the authentication application is accessed on the device when the authentication application is logged in.

11 . A device comprising:

a memory configured to store instructions; and

one or more processors coupled to the memory and configured to execute the instructions to cause the device to:

determine a login authentication device of a to-be-authenticated application, wherein the login authentication device comprises an authentication application, and wherein the authentication application is logged in, wherein the one or more processors are further configured to execute the instructions to cause the device to further determine the login authentication device by:

sending a query request to one or more electronic devices to enable the one or more electronic devices to separately determine whether the one or more electronic devices have an account authorization capability of the authentication application, wherein the query request comprises first identification information and account login indication information;

receiving, from at least one electronic device having the account authorization capability in the one or more electronic devices, a query response comprising a device identifier of the at least one electronic device;

determining a unique electronic device as the login authentication device in response to the at least one electronic device comprises the unique electronic device; and

in response to the at least one electronic device comprises multiple electronic devices:

displaying the multiple electronic devices on a screen for selection by a user; and

determining an electronic device selected by the user as the login authentication device;

send, to the login authentication device, a first login authentication request comprising the account login indication information and the first identification information; and

obtain, from the login authentication device, a first login authentication response comprising indication information of a login authentication result that is based on the account login indication information and the first identification information.

12 . The device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the device to further determine the login authentication device by identifying a trusted network comprising at least two electronic devices that have a trusted relationship, wherein the trusted network comprises the one or more electronic devices.

13 . The device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the device to receive, from a login authentication platform, the first login authentication response, wherein the first login authentication response is based on a second login authentication response received by the login authentication platform from the login authentication device.

14 . The device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the device to:

send, to a login authentication platform, a second login authentication request comprising second identification information of the to-be-authenticated application; and

receive, from the login authentication platform, a second login authentication response comprising the first identification information and the account login indication information.

15 . The device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the device to:

enter a user interface of the to-be-authenticated application when the indication information indicates that login authentication has succeeded; and

exit the to-be-authenticated application when the indication information indicates that the login authentication has failed.

16 . The device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the device to:

enter a user interface of the to-be-authenticated application when the indication information indicates that login authentication has succeeded; and

pop up a window indicating that the login authentication has failed when the indication information indicates that the login authentication has failed.

17 . A device comprising:

a memory configured to store instructions; and

one or more processors coupled to the memory and configured to execute the instructions to cause the device to:

receive, from a login authentication initiation device, a first login authentication request comprising identification information of an authentication application and account login indication information;

determine, in response to first login authentication request and based on the authentication application being installed and accessed on the device, that the device has account authorization capability of the authentication application;

display, based on the first login authentication request and the account authorization capability, an account login interface of the authentication application, wherein the account login interface comprises a first button indicating to approve authorization and a second button indicating to reject the authorization;

obtain an operation instruction generated when a user performs a tapping operation on the first button or the second button, wherein the operation instruction comprises a login authentication result; and
