Manually synchronize Contacts & Calendar (iOS apps) using CardDAV/CalDAV

Update 07/03/2026

This guide explains how to connect the Contacts and Calendar iOS (iPhone, iPad…) apps with the contacts & calendars hosted by Infomaniak.

 

Introduction

  • Rather than the manual configuration below, it is recommended to use the .mobileconfig configuration profiles offered by Apple.
  • Infomaniak contacts & calendars are linked to your Infomaniak account; when you log in to ksuite.infomaniak.com/contacts or /calendar, you will likely need to perform two-factor authentication (2FA) during login.
    • In this case, an application password is required to establish synchronization between your device and Infomaniak tools.
    • But don't worry, creating such a password is offered as part of the configuration wizard.

 

Manual configuration (contacts & calendars)

Obtain your login information

To obtain the CardDAV/CalDAV synchronization username and password:

  1. Click here to access the Infomaniak configuration tool (online service https://config.infomaniak.com) — log in if necessary to your Infomaniak account for the Organization where your email address is managed.
  2. Select a device other than iOS (this is to obtain your username):
  3. Choose Linux:
  4. Choose Contacts or Calendars:
  5. Choose the specific service that needs to be synchronized.
  6. Tap the right arrow several times, then tap the title of the manual synchronization tab:
  7. The information displayed below allows you to obtain:
    1. your username (e.g., AB12345)…
    2. application password if two-factor authentication is enabled or the password for your Infomaniak user account if you have not enabled 2FA.
    3. For the server address, use only sync.infomaniak.com.

 

Using the login information

With this information, all you have to do is add your accounts according to Apple's instructions:

  • Go to Settings > Contacts > Accounts > Add Account.
  • Tap Other, then Add CardDAV Account and enter the account and server information.

Do the same for the Calendar app:

  • Go to Settings > Calendar > Accounts > Add account.
  • Tap Other, then Add CalDAV account and enter the account and server details.
