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.

Pro tip: if you do insist on using Google scroll to the bottom until you see a notice like the one below.

You can then click on the complaint to see the URLs that were removed.

They’ve wisened up a bit and now require a (throwaway) email to access the links, but chances are that if you’re looking for something more obscure, the link you seek is still there.
