Easily generate a global configuration file for your service, or one tailored to each user.
Easy deployment of user accounts
Administrators can easily create, update, or adjust account information from a central dashboard, without requiring end-user intervention. Then, choose the most convenient account configuration method for your users: entering credentials, scanning a QR code, clicking a link sent via email, or using Single Sign-On authentication via OpenID Connect.
Integration with company directories
Each user can have their own personalized contact list, but it is also possible to configure an LDAP server for contact search or synchronize contacts through a company directory using the CardDAV protocol.
