Connect Apple Calendar

Apple Calendar connects via CalDAV using an app-specific password — a separate password generated from your Apple ID that keeps your main credentials private.

You will need an Apple ID with iCloud Calendar enabled and two-factor authentication active (required to generate app-specific passwords). Manage your Apple ID at appleid.apple.com.

Step 1: Generate an app-specific password​

Create the password from your Apple ID settings before connecting.

caution

Use an app-specific password, not your regular Apple ID password. CalendarPipe will not accept the latter.

  1. Go to appleid.apple.com and sign in.
  2. Navigate to Sign-In and Security > App-Specific Passwords.
  3. Click +, label it CalendarPipe, and click Create.
  4. Copy the generated password — Apple will not show it again.

The password looks like abcd-efgh-ijkl-mnop. Keep it safe until you finish the connection.

Step 2: Connect in CalendarPipe​

  1. Navigate to Calendar Connections in the CalendarPipe sidebar
  2. Click Add Connection
  3. Select Apple from the list of providers

Revoke access​

To disconnect CalendarPipe from your Apple Calendar, revoke the app-specific password:

  1. Go to appleid.apple.com > Sign-In and Security > App-Specific Passwords.
  2. Click x next to the CalendarPipe password and confirm.

Revocation takes effect immediately — CalendarPipe loses access to your calendars on the next sync attempt.

Troubleshooting​

  • "Authentication failed" error -- Make sure you are using an app-specific password, not your regular Apple ID password. If the password was recently generated, wait a minute and try again.
  • No calendars found -- Verify that iCloud Calendar is enabled in your Apple ID settings (System Settings > Apple ID > iCloud > Show More Apps > iCloud Calendar).
  • 2FA not enabled -- App-specific passwords require two-factor authentication. Enable 2FA in your Apple ID settings before generating an app-specific password.
  • Password expired -- App-specific passwords remain valid unless manually revoked. If your connection stops working, generate a new app-specific password and reconnect.
