@jmac3665 😂 there is an annoying but completely functional workaround for the 2FA pop up issue: 1. Make dummy account on Mac, log in to iCloud, and enable 2FA. 2. Log out of iCloud and the account, then delete the account. 3. Add a second iCloud account on your iOS device in Passwords & Accounts. 4. Rejoice. You now have full 2FA including the pop ups for both accounts on the one device.
