iCloud and Yahoo

iCloud and Yahoo don't offer OAuth for third-party calendar apps. CalKeep connects via CalDAV with an app-specific password — a one-time-generated credential that's separate from your main account password.

iCloud setup​

Generate an app-specific password​

  1. Sign in to appleid.apple.com.
  2. Under Sign-In and Security, click App-Specific Passwords.
  3. Click Generate an app-specific password.
  4. Label it CalKeep and click Create.
  5. Copy the 16-character password (looks like abcd-efgh-ijkl-mnop). You won't see it again.

Connect in CalKeep​

  1. Go to Settings → Connected Accounts.
  2. Click Connect iCloud.
  3. Enter your Apple ID email and the app-specific password.
  4. CalKeep validates the credentials and imports your calendars.

Yahoo setup​

Generate an app password​

  1. Sign in to Yahoo Account Security.
  2. Click Generate app password.
  3. Pick Other app and label it CalKeep.
  4. Copy the password Yahoo generates.

Connect in CalKeep​

  1. Go to Settings → Connected Accounts.
  2. Click Connect Yahoo.
  3. Enter your Yahoo email and the app password.
  4. CalKeep validates and imports.

What's synced​

  • All calendars on the account.
  • Events with title, description, location, attendees, and recurrence rules.

CalDAV doesn't expose contacts the way Google and Microsoft do, so the CRM features stay calendar-driven for these accounts.

Sync cadence​

CalDAV is poll-only (no push). CalKeep polls every 2 minutes, so updates appear within ~2 minutes of a change on the provider side.

Updating credentials​

If you regenerate your app-specific password, update it in CalKeep at Settings → Connected Accounts → [your account] → Update credentials. CalKeep won't sync until the new password lands.

Troubleshooting​

  • Connection fails immediately: double-check that you used the app-specific password, not your main account password. iCloud and Yahoo block main-password CalDAV access.
  • Two-factor enabled but you don't see the app-password screen: make sure 2FA is fully enabled on your account. Some account states show a different settings UI.
