Configure Multiple Users - WeiFei365/shadowsocks GitHub Wiki

Currently Python and Go servers support multiple users.

You can use different passwords on different ports like this:

{
    "server": "0.0.0.0",
    "port_password": {
        "8381": "foobar1",
        "8382": "foobar2",
        "8383": "foobar3",
        "8384": "foobar4"
    },
    "timeout": 300,
    "method": "aes-256-cfb"
}

If you want to build a user management system, check the Manager API.
