Ubisofts Uplay: they have serious problems with user accounts and log in. They hoisted a 2factor authentication on it, but some thing's not right with it: fails to accept the 2 factor codes for many users saying code is wrong, locking people out from there accounts and purchased games, even locking out their access to support which may be the only way of resolving these issues. So frustrating that something as fundamental as user login is botched up by a major software company.
