Microsoft is making changes to let users use their Skype account credentials to sign in to other services. The company notes that depending on the service you’re trying to access, you’ll still need to enter an email address, but on certain Microsoft services, such as Xbox Live, Office, OneDrive, and Outlook.com, you’ll now be able to use your Skype ID.
While this should be a good news for many users, remember that for about three years, the software giant has been trying to get users to link their Skype account with the Microsoft account, which is the reason why today you can sign in to Skype using your Microsoft account credentials.
However, when the new changes are live now, if you haven’t linked your accounts, you’ll have to update your Skype account with your Microsoft account to access other services with your Skype ID. After merging the accounts, you will continue to be able to use your Skype name with your Microsoft account password to sign in to other services.
Microsoft also notes that if you’ve noticed the new changes on the Skype sign-in screen, password change, and account recovery flow, it’s because everything is now managed by the company, as part of the effort to simplify access using a single username and password across services.
