With Apple's devices, you can copy-paste your 2nd factor token between devices, which makes things much more convenient. Although cloud copy-paste is still significantly slower than tapping "Allow" in a notification, it's lower friction than manually typing those numbers.

Although the security of cloud copy-paste I haven't investigated...

I've not checked how it works, but I don't think Universal Clipboard pushes the data that's being copy-pasted via the cloud. I've certainly used it to copy Wifi access codes from my phone to laptop when neither device had internet access, so I think it's implemented using peer-to-peer Bluetooth/Wifi.
