Any popular password manager, especially an online one, is likely to be compromised. Security has to make a successful attack more expensive than the target is worth. How much is all data in all accounts of an online password manager worth? That is a very attractive target, and generally in IT it is much cheaper to attack than to deend. I doubt any password manager vendor has the resources necessary to truly protect their users. At least, if you are not paying top dollar for security, don't expect much.
