Macbook pro connexion

When I want to connect my mycloud, it asks me: “Enter your name and password for the MyCloud server…” then I either log in as a guest or as a registered user with a name and password. But bad luck he tells me that the password is incorrect, so I use the same one as for my MyCloud account…
If anyone can help me?
