Claim:
1. A method, comprising: obtaining a login request from a user for logging into an account of a first account system; determining, from property information stored in a current login host, property information of a second account system, wherein the second account system is designated as a related account system of the first account system, and the property information of the second account system includes data that is generated during an operation of the second account system on the current login host, the data including multiple account identifications of the second account system; generating login verification information comprising at least the property information of the second account system; performing irreversible processing on the property information of the second account system prior to sending the login verification information to a server; and sending the login verification information to the server, wherein the property information of the second account system in the login verification information is a basis for determining that a login is reliable when the server compares the property information of the second account system with pre-stored reliable property information that corresponds to the account of the first account system and when an intersection exists between the property information and the pre-stored reliable property information and the intersection satisfies a pre-set criterion, the second account system and the first account system being different account systems, the pre-set criterion including the intersection between the multiple account identifications of the second account system included in the property information and one or more account identifications of the second account system included in the pre-stored reliable property information is more than a preset threshold.
