Using PingID mobile app on your Android to get a one-time passcode with which to authenticate, so you can access your Apple Mac machine.
If you don't have internet access from your mobile device temporarily, you can still authenticate using PingID mobile app by generating a one-time passcode (OTP). The one-time passcode is unique, and can only be used once. Only the one-time passcode that appears on your device at the time that you sign on to your account is valid for authentication.
Note:
You'll only be able to view and use the one-time passcode if permitted by your organization's policy.
