Passwordless and Universal Login at the same time

Hello

I have an auth0 tennant with several applications, all of them are SPAs, they all share the Universal Login with Username and Password and database connections, one per each application.

Now I have a requirement to create a Mobile App, and I want to use Passwordless for the Mobile App based on the email, and disconnected from the other databases.

My issue is that when I create the Application of type Native and do the integration:

  1. It keeps using my Universal login with user and password
  2. I try the login using the curl commands for an embedded Auth as an alternative, disabling signups, but the result I get is {“error”:“bad.connection”,“error_description”:“Public signup is disabled”}% … and I don’t have where to add the “valid” emails of people that can log into my app.

How can I achieve the second one, assuming that the first one is not possible to share passwordless and password authentication in the same universal login based on the Application.

Thanks

Hi @mpojeda84,

Welcome to the Community!

You can customize the code in the hosted login page to initiate passwordless or email/password based on which client the request is being made for. Simply add a conditional based on config.clientID.

I basically combined the two defaults, with a an if/else.

I tested this out briefly and everything seems to be working correctly. Replace {CLIENT_ID_GOES_HERE} with the client ID of the app you want to be passwordless. Also, be sure to set up which connections are enabled for your application in application settings.
