Abstract: A first request to log in to a suspended account is received. The first request includes an operation code. A determination is made that the operation code satisfies a predetermined condition. In response to the determination, the suspended account is obtained based on the operation code and the suspended account is logged in to.

Abstract: Techniques for flexibly controlling data uniqueness which are applicable to different types of data that require different data uniqueness control. Control information mapped by a data storage space of a database is determined. The control information and data to be written into the data storage space is combined to obtain a combination result. The techniques of the present disclosure determine whether there is another combination result that is the same as the combination result. The techniques of the present disclosure, in response to determining that there is another combination result that is the same as the combination result, reject to write into the data storage space the data to be written into the data storage space of the database; or modify the another data in the database.

Abstract: A method for password setting and authentication is provided. The method includes receiving a password setting request and acquiring a reference character string and reference input duration information. The reference input duration information may be associated with a character at a position of the reference character string. The method may further include storing the reference character string and the reference input duration information, receiving a password authentication request, and acquiring an authentication character string input by a user and authentication input duration information. The authentication input duration information may be associated with a character at the position of the authentication character string. The method may further include determining whether password authentication is successful based on the authentication character string, the authentication input duration information, the reference character string, and the reference input duration information.

Abstract: Embodiments of the present application relate to a method and system for managing user accounts. The method includes receiving a registration request from a current user, wherein the registration request comprises a login name main part, determining, in a database, whether a conflicting old user exists, wherein a conflicting old user corresponds to another user that has a conflicting login name main part that is the same as the login name main part received in connection with the registration request, in the event that a conflicting old user exists, executing a login password differentiation process that requires a user to register a different login password that is different from a login password associated with the conflicting old user, and storing the different login password to the database in connection with a registration of the current user.
