If you are currently using Facebook to log into Skype, you should note that starting from next year, you will no longer be able to long into Skype using your Facebook account as Microsoft is pushing its unified log-in solution.
While the upcoming change will not be affecting users who use the service regularly, it will ultimately affect those who use the service more rarely. However, switching away from the Facebook login is pretty simple and all of your activities will be transferred during the process.
The company revealed on the its support page, “As we continue to roll out the new Skype, we’re discontinuing the option to login via Facebook in January 2018 and will streamline all Skype logins via your Microsoft account. Using a Microsoft Account will enable you to login-in via single sign-in, unlocking all your Microsoft services — including Skype, Office Online, Outlook, OneNote, OneDrive, and more — in one experience, with just one password. Currently, using your Facebook account to sign in to Skype is not supported on Skype for Windows 10, the new Skype for Android and iPhone, and the new Skype for Windows, Mac, and Linux.”
On the other hand, if you cannot change your log in method before the change takes place, you will be fully refunded and your Skype account will be canceled.
