Change in Owncloud login

From 5 December, the Microsoft single sign-on (SSO) will be introduced, changing the way how you access the Owncloud environment. The Owncloud login update aims to ensure two-factor authentication, which increases security and protects user accounts. While previously it was possible to log in with a username and password, now it takes place via the Microsoft account. The change will not affect any other features of Owncloud. 
More information is available in the guide for activating two-factor authentication.
