Connect Apple Calendar to Cal ID so your iCloud events sync with your availability and prevent double-booking. Because Apple does not offer a standard OAuth flow, you’ll sign in with an app-specific password instead of your regular Apple ID password.
An app-specific password is a one-time code generated at appleid.apple.com that lets a third-party app access your iCloud data securely. You’ll create one in the steps below and paste it into Cal ID, so your real Apple ID password is never shared.
