Sharing authentication between native app & two websites


We’ve got a mobile app (Xamarin) and two websites ( and using Auth0.js

A user can log into the mobile app, and then can be redirected to Also, use can go from to or the other way around.

As Custom Connections are not supported in hosted landing pages, we had to use custom, embedded authentication. This works superb.

I’ve been looking at SSO for Auth0, they all talk about hosted login pages. Also this post: Sharing authentication between 2 sites does not answer my questions.

What I’m thinking, is to share the access token via the query string, and this way implement SSO. Is this supported? Is there an API for this?
