flutter login example

Hi seankang​ ,

Let me try to restate the question:
- you have a website hosting your app : http://www.website.com/app (or something like that)
- you are working on an app : com.website.appName

My understanding is that the URI for both is used in looking up the password in the Vault. Some applications/sites have a similar fundamental domain like "www.website.com" and "com.website.app" (just reversed).  Other apps/websites have login services that have completely different. 

In the case of a different service, the user just has to manually look up the password and then they will be presented with the option to save or update the password.

I don't see any content about how to make these work best, but typically if you follow these guidelines (link below) and a similar URI structure it should work.  Now if you are looking at doing PassKeys there is a bit more configuration on the Apple & Android side (they have lots of docs for this).

Let me know if this helps.
