Dear Community,

I wish to implement Passwordless Authentication using Okta APIs, similarly to the Okta OIE sign in widget with flexible sign in options. Currently there is no support for primary authentication using flexible Authenticators via APIs.

Thanks

Hello,  
Okta does not document the interaction code flow the way it does with /authn, but the auth-js SDK does support IDX. Specific documentation for using the SDK in IDX flows can be found at,

> Secure, scalable, and highly available authentication and user management for any app.
