To keep security for the mongodb server, we can create an authorized machanism.

db.createUser(
    {
        user: "user1",
        pwd: "passwd",
        roles:[{"role": "userAdminAnyDatabase", "db": "admin"}]

    }
)

db.createUser(
    {
        user: "user2",
        pwd: "passwd
 
",
        roles:[{"role": "readWrite", "db": "database"}]

    }
)
