Microsoft’s implementation is the worse. I sometimes have a hard time deciphering the captcha. Why do they need that in an iOS app? Are robots emulating people from an iPhone?

I’m thinking about how Overcast uses a token linked to the user’s iCloud account and doesn’t require a username and password if you only use iOS devices. You can optionally add a username and password to access the web client.
Many of the more sophisticated ones prefer emulating mobile application requests to web requests, so yes.
