This application is a UnifiedPush distributor that works with the Nextcloud application associated (https://github.com/UP-NextPush/server-app). The SSO login requires the Nextcloud App to work : https://f-droid.org/packages/com.nextcloud.client/ . You can also connect directly to Nextcloud. We recommend using an application password.
