Microsoft offers the ability to link a Skype and Microsoft Account together to make sign-in and security easier.
If you already enabled this months ago, it turns out that Microsoft has kept your original Skype account password separate so that it can still be used to access the service with a Skype username.

) is a telecommunications application software product that specializes in providing video chat and voice calls between computers, tablets, mobile devices, the Xbox One console, and smartwatches via the Internet and to regular telephones. Much of the service is free, but Skype Credit or a subscription is required to call a landline or a mobile phone number.
Skype additionally provides instant messaging services. Users may transmit both text and video messages, and may exchange digital documents such as images, text, and video.

If you've already linked a Microsoft Account to Skype, then you'll need to "update" your Skype account to ensure it's fully merged over at Microsoft's account page.
