actor user as User
participant page as Page

box rgba(101, 63, 232, 0.5) Blazor.Auth
participant userServiceServer as IUserService (Server)
participant blazorClient as Client Machine
participant blazorServer as Blazor Server
end

participant authService as IAuthenticationService (Server)

page ->>+ userServiceServer: SignInAsync(signInPayload)
note over page,userServiceServer: Resolve IUserService from DI<br/> and call it's `SignInAsync` method.

userServiceServer ->>+ blazorClient: Remote JS Interop
blazorClient ->>+ blazorServer: HTTP Request to <br/> Sign-In endpoint
blazorServer ->>+ authService: SignInAsync(signInPayload)
authService ->> authService: Your server-side sign-in logic

authService -->>- blazorServer: AuthenticationResult
blazorServer -->> blazorServer: Update authentication cookies

blazorServer -->>- blazorClient: AuthenticationOperationInfo
note over blazorClient,blazorServer: Updated cookies will be<br/>attached to the HTTP response.

blazorClient -->>- userServiceServer: AuthenticationOperationInfo

userServiceServer -->>- page: AuthenticationOperationInfo
page -->>- user: Continue, <br/> e.g. redirect to home page, <br/> or other custom logic
