-{% include faq.html question="Wo kann ich meinen Account bearbeiten?"

-  [login.infra4future.de](https://login.infra4future.de) verwaltet werden,
-  werden auch die Zugehörigkeiten zu einzelnen Gruppen dort verwaltet.

-  Natürlich gibt es auch Gruppen bzw. Teams in Mattermost und Nextcloud; diese
-  werden möglichst automatisch auf einem Stand mit login.infra4future.de gehalten.
-  Leider gilt das nicht anders herum — fügt also bitte neue Leute nicht direkt

-  ihnen einen Einladungslink. Andernfalls kann es sein, dass sie automatisch

-  erstellen. Diese können sowohl benutzt werden, um neue Accounts zu erstellen,
