> available to the masses in the form of a standard adopted by Apple, Google, and Microsoft that allows for cross-platform and cross-service passkeys. Any way to use this standard if you're not Apple/Google/Microsoft? I'd prefer an option that Apple/Google/Microsoft can call a service (that I control and authorize). I want to be able to self host such a service or have an open marketplace that can compete to serve this service.
