USPS’ website does this, sort of.

If their text service is down it’ll let you know and just skip the 2FA process even though normally they offer an option to get the code via email.

The fact that they do this is bad enough, the fact that this happens so often that I’ve seen this at least a dozen times is even worse.

Good instinct, here’s a BBC source.

Edit: Apparently this is old news? Or the news is that lawsuits have commenced?
