I once created a SAAS application that did not have the "ordinary" workflow that people expect these days - email/password or social login.

People hated it and actually took the time to complain.

The lesson for me - make your auth process precisely what people expect - if there's feedback, it should be about your product, not about the signup process.

Signup process is not a feature - it's plumbing.

In the case of this new product / service - I note the headline is almost unrelated to what the product does - it's a headline about how the auth works on this - the technology something is built with shouldn't be the marketing message.
