I try to add an authentication method in Blazor 8 but only the last method will work.

With the follwing code i am able to login with cookie:

...
builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
    .AddMicrosoftIdentityWebApp(opts =>
    {
        builder.Configuration.GetSection("AzureAd").Bind(opts);
    });
builder.Services.AddAuthentication(options =>
            {
                options.DefaultScheme = IdentityConstants.ApplicationScheme;
                options.DefaultSignInScheme = IdentityConstants.ExternalScheme;
                options.DefaultSignOutScheme = IdentityConstants.ExternalScheme;
            }).AddIdentityCookies();
...

I can also see to button “OpenIdConnect”. If i click the button i can see it will try to login but will redirect back to login. At the console i can see the log “IDX21310: OpenIdConnectProtocolValidationContext.ProtocolMessage.AccessToken is null, there is no ‘token’ in the OpenIdConnect Response to validate.”

If i change my code like this:

...
 builder.Services.AddAuthentication(options =>
             {
                 options.DefaultScheme = IdentityConstants.ApplicationScheme;
                 options.DefaultSignInScheme = IdentityConstants.ExternalScheme;
                 options.DefaultSignOutScheme = IdentityConstants.ExternalScheme;
             }).AddIdentityCookies();
  builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
     .AddMicrosoftIdentityWebApp(opts =>
     {
         builder.Configuration.GetSection("AzureAd").Bind(opts);
     });
...

I am able to login with the Microsoft Account, but now i cant login with credentials by Username and Password.
Now i only will be redirected to “home” but i am not logged in.

What i am doing wrong?
Thanks in advanced.

I have try so many things founded. I like to login both with Microsoft Identity and over credentials by JWT or Cookies.
