Skype has revealed that people can now sign up for the VoIP/messaging service using a Microsoft account. This user works great if you prefer to have less login credentials. The Windows Phone app has also been updated with a number of security improvements plus an indicator that shows you when the person on the other side starts typing. Skype will now require a Microsoft account when registering for a new account through the app. The new version of the app is only available for Windows Phone 8.
