Creating an iCloud app-specific password

Apple requires users to use app-specific passwords for all third party applications such as OnceHub. An app-specific password is a single-use password for your Apple ID that lets OnceHub securely access the information you store in your iCloud calendar. This access method enhances your security and privacy, and requires that you turn on Apple two-factor authentication or Apple two-step verification. Watch the video or read the instructions below.

How to create an app-specific password

  1. Sign in to your Apple ID account page.
  2. Turn on Apple two-factor authentication if it is not on already. On older devices use Apple two-step verification instead.
  3. In the Security section of your Apple ID account page, click Generate Password below App-Specific Passwords and give it a title (e.g. ScheduleOnce or any name).
  4. Once the app-specific password is generated, copy and paste it into the iCloud connection box in the ScheduleOnce Calendar integration page.

More information

  • No need to keep the app-specific password that you generated. It is a single-use password, and you can always generate another one (up to 25 total).
  • App-specific passwords are valid until you change your primary Apple ID password. Once you do, all your existing app-specific passwords are automatically revoked, and must be generated again. All third-party applications must be reconnected with new app-specific passwords, including your OnceHub account.
