Constantly unsatisfied with desktop email clients, I tend to try new ones once in a while. Just now I tried to use Airmail with one of my lesser used Google Mail accounts (unimportant enough that I did not enable two-step verification.) and was most certainly slightly confused when it refused to connect.

I was even more confused when this showed up in the mailbox of the recovery account:

You can switch to an app made by Google.

No. I don’t want to switch to an app made by Google – I want IMAP.

Thanks anyway. As far as I know, this is a new thing and it is a bit worrying.
