@MahdiElahi thanks for contacting us.

The Identity pages require access to the underlying HttpContext and only work in SSR mode. They don't work in interactive mode.

@MahdiElahi Please provide your repro as a public github repository, otherwise we can't look at it.

This is not something that we provide out of the box. You'll have to create your own implementation using the new identity endpoints.

@javiercn it's means in register/ login / changepassword / ...(all pages use identity and Http Context ) we must use ssr mode how to do it ? please show an example that use without ssr mode or another way?

I was having a similar problem. In my case the problem was caused by @rendermode="InteractiveServer" in the HeadOutlet and Routes. Strangely when I had this in there I was getting the cookies error.

    <HeadOutlet @rendermode="InteractiveServer"/>
</head>

<body>
<Routes @rendermode="InteractiveServer"/>

I really have to read a bit more about these render modes, my knowledge is lacking.

@MahdiElahi I checked your ForumProject and made a couple of changes, now it is working Here is a pull request: https://github.com/MahdiElahi/AuthProject_Blazor8/pull/1

Hope this helps/

stile I have this issue

Did anyone figure out how to create interactive login page? It is espectially useful if we are connecting to existing/external API that uses JWT Bearer token. After httpClient calls the API, we need a way to securely persist the token and use it for further calls.

dotnet / aspnetcore
