The invention provides a multi-signature-based login method, which is applied to a server and a client. The server is provided with M private keys, and M is an integer which is greater than or equal to 1; the client is provided with N private keys, and N is an integer which is greater than or equal to 2. The method comprises the following steps that the server generates a multi-signature address for the client and presets M+X private keys to sign the multi-signature address, so that the client logs in to the server, wherein X is an integer which is smaller than or equal to N; the client utilizes the X private keys to sign the multi-signature address for the first time; the server affirms that the signature of the client is an available signature; and the server utilizes the M private keys to sign the multi-signature address for the second time, so that the client logs in to the server. According to the method and the system, the secure login of a user is guaranteed. 本发明提供种基于多重签名的登录方法，应用于服务器和客户端中，服务器拥有M个私钥，M为大
