Anthropic, the company behind the Claude AI, is adding identity verification, "for a few use cases". You can read the support document here. It's not immediately clear what those use cases are. Much of the push-back from Internet buzz on the subject seems to be over their choice of Persona as the 3rd party used for verification. It's interesting to see how this develops. I've seen some claimed users say they were cancelling their accounts, but I haven't heard of anyone cancelling because they were being forced to do the verification. Worth following.
