As of 12 March 2018 new users will only be able to join the Microsoft Educator Community using either a personal Microsoft account or an Office 365 account. According to Sonja Delafosse - Microsoft Senior Education Manager, "We’re phasing out accounts so we can optimize user experiences with Office 365 and Microsoft personal accounts".
After 8 May 2018 Microsoft Educator Community users who are currently accessing their accounts through Facebook, Skype or Twitter email addresses will lose access to their account and badges, certifications and any published content will be permanently deleted.
Don't lose the badges, certificates, points and connections you have worked so hard to achieve. Log in to the Microsoft Educator Community now to convert your login details to a Microsoft account.
