Install a trusted CardDAV sync adapter, such as DAVx⁵. In the Vault, open Settings → Security → App & device access, create a LightDrive client password that includes Contacts for the Android device, and copy it when displayed. Choose Contacts only, or Contacts & calendars if the adapter also synchronizes calendars.
- URL:
https://dav.lightdrive.one/USERNAME/contacts/ - Username: your full LightDrive email address
- Password: a LightDrive client password that includes Contacts
Select the discovered Contacts collection, enable synchronization, and grant the adapter contacts and background permissions. The contacts then appear in Android apps that use the system contacts provider.
Choose the LightDrive account when creating a contact. A contact saved to the phone-only or Google account will not be sent to LightDrive. Your main Vault password, Vault app passwords, and Email-only passwords do not work for CardDAV.
