Annoyed with Apple's decision to force 2 factor authorisation on all iCloud accounts: I used to use Inky app on the Mac & Outlook on iOS to access the Men"s Shed iCloud email account on non-shed days.
It's the 2nd factor that the Shed lacks. Any contact phone numbers, either mobile or fixed line are individual members' devices. The Shed has a single device, the iMac.
On the Mac, I've set up an Epichrome single-site browser for iCloud and I use the iCab Mobile browser on iOS to access iCloud without it defaulting to the mobile view as Safari does.
