.Net 5 RC2 - Blazor Wasm - AAD B2C SignUpSignIn catch error 'AADB2C90118' to start Password Reset userflow

[TeguSolutions]

Hello,

I am working on a Blazor Wasm project. I have just updated the project to the actually latest .Net 5 SDK, because I needed the LoginMode = "Redirect" feature for AAD B2C.
The AAD B2C is correctly set up and working from Azure and from the app as well.
The used userflows are:

• Sign up and sign in (Recommended)
• Password reset (Recommended)

But I would like to initiate the password reset from the signup/signin flow. For this I need to catch the 'AADB2C90118' error message as I read, although the Authentication component is not triggered at all, meanwhile the expected response is visible for a moment. After some redirects the signup/signin page is shown again,

The used packages are:
Microsoft.AspNetCore.Components.WebAssembly - 5.0.0-rc.2.20475.5
Microsoft.AspNetCore.Components.WebAssembly.DevServer - 5.0.0-rc.2.20475.5
Microsoft.Authentication.WebAssembly.Msal - 5.0.0-rc.2.20475.5
Microsoft.Extensions.Http - 5.0.0-rc.2.20475.5
System.Net.Http.Json - 5.0.0-rc.2.20475.5

The Blazor app is .Net hosted with the server app, although it is not relevant because I am running without it.

The related stackoverflow question is:

Can you please check it and give me feedback, that it should work, or it is a bad approach from me?

@Satukan thanks for contacting us.

This is not a feature we support at the time, since there isn't/wasn't msal support for it at the time. We might consider supporting this in the future if we hear more feedback about it.

[TeguSolutions]

Alright, I understand and the status is clear.
Thank you.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time.

@Satukan I'm keeping this open so that we can consider it on our planning process for the next release

@TeguSolutions, we are sticking to the "Standard" user flows and the redirect (instead of popup) login mode for our app (WASM backed by API management) per #23638 until the next major release which will hopefully address this.

Hello,
I need this feature as well... Can't see how I could use B2C in my blazor app if my users can't reset their password whenever they forget it.

Just a note: the msal library has been upgraded in 5.0.3: #29226

This seems obsolete because AD B2C implemented self-service password reset, which is entirely done via the AD page.

This is not needed. See Set up a password reset flow - Azure AD B2C | Microsoft Docs for details
