I have some issues with this guide. I find it very odd how the very first step of the guide is to “erase all content and settings” but it doesn’t really mention all the caveats around this. There really should be warnings or a separate guide about doing this safely because if some people do that, they could lock themselves out of MFA-protected accounts.

Lastly, about Apple Configurator, it seems like it only works on macOS, so probably this won’t work if you have an iPhone but no macOS device, right?

We are close to the “we should put a warning label on the microwave that don’t dry your cat in it”. At some point it’s not a blog authors responsibility to make you understand that “erase all content” erases all content.
