Authentication in Skype is awful. At one point, for reasons beyond me, I ended up having two accounts:

* One account required me to log in with a username, and was associated with my main email address. * The other account required me to log in with my main email address.

In a way, they were both related to the same email, but different accounts. This shouldn't even have been possible, but it seems that one was an old MS account, and the other was an old Skype account. My roster ended up being split half and half between the two.
