How to add iCloud calendar on Android

- The password needs to be filled with an application specific password. It has the format of XXXX-XXXX-XXXX-XXXX. Instructions to generate it will be shown below.

7. Setup 2 factor authentication

All third-pary applications (like OneCalendar) require an app-specific password for connection to iCloud due to Apple security measures. In order to do this it's first required to setup 2 factor authentication. You only need to set this up once if you haven't done so already. This can be done on you iPhone/iPad or on your Mac.

8. Create app specific password

- Sign in to your Apple ID account page.

- In the "Sign-in and Security" section, click "App-Specific Passwords."

- Click "Add"

- Follow the steps on your screen.

- After you generate your app-specific password, enter or paste it into the OneCalendar password field.
