Binding server accounts

A computer-implemented method, comprising:

• obtaining, from a first server and by a second server, an identity authentication request or a binding consulting request, wherein the identity authentication request or the binding consulting request comprises user identity data corresponding to a first account on the first server;
• in response to obtaining the identity authentication request or the binding consulting request, determining one or more second accounts on the second server that correspond to the same user identity data as the first account;
• sending, by the second server and to the first server, authentication feedback data or consultation feedback data, wherein the authentication feedback data or the consultation feedback data comprises account data of the one or more second accounts, so that the first server determines one or more target servers and sends, to each target server, a respective account binding request;
• obtaining, by the second server, an account binding request sent by the first server;
• and
• in response to obtaining the account binding request, binding, by the second server, at least one of the one or more second accounts to the first account.

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• obtaining, from a first server and by a second server, an identity authentication request or a binding consulting request, wherein the identity authentication request or the binding consulting request comprises user identity data corresponding to a first account on the first server;
• in response to obtaining the identity authentication request or the binding consulting request, determining one or more second accounts on the second server that correspond to the same user identity data as the first account;
• sending, by the second server and to the first server, authentication feedback data or consultation feedback data, wherein the authentication feedback data or the consultation feedback data comprises account data of the one or more second accounts, so that the first server determines one or more target servers and sends, to each target server, a respective account binding request;
• obtaining, by the second server, an account binding request sent by the first server;
• and
• in response to obtaining the account binding request, binding, by the second server, at least one of the one or more second accounts to the first account.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• obtaining, from a first server and by a second server, an identity authentication request or a binding consulting request, wherein the identity authentication request or the binding consulting request comprises user identity data corresponding to a first account on the first server;
• in response to obtaining the identity authentication request or the binding consulting request, determining one or more second accounts on the second server that correspond to the same user identity data as the first account;
• sending, by the second server and to the first server, authentication feedback data or consultation feedback data, wherein the authentication feedback data or the consultation feedback data comprises account data of the one or more second accounts, so that the first server determines one or more target servers and sends, to each target server, a respective account binding request;
• obtaining, by the second server, an account binding request sent by the first server;
• and
• in response to obtaining the account binding request, binding, by the second server, at least one of the one or more second accounts to the first account.
