  Hi

  Have you tried overriding Login.cshtml in backend you can write your custom logic there.

  Hi,

  I'm using Angular with Resource Owner Password Flow so I don't think changing Login.cshtml will help me.

  Besides, the public login should occur automatically when opening any page of the application. Not only the login page.

  hi as a workaround, can you do something like this? With this method, you won't need to reload the page.

  export class AppComponent {
    config = inject(ConfigStateService);
    authService = inject(AuthService);
    router = inject(Router);
  
    constructor() {
      const currentUser = this.config.getOne('currentUser');
  
      if (currentUser == null || currentUser.id == null) {
        const loginParams: LoginParams = {
          username: 'admin', // change with your username
          password: '1q2w3E*', // change with your password
          redirectUrl: '/',
        };
        this.router.navigateByUrl('/account/login').then(() => {
          this.authService
            .login(loginParams)
            .subscribe();
        });
      }
    }
  }

        }; 
        this.router.navigateByUrl('/account/login').then(() => { 
          this.authService 
            .login(loginParams) 
            .subscribe(); 
        }); 
      } 
    } 
  } 
  

  Thanks but with your workaround, the login page is displayed for 1-2 seconds before being redirected to the main page. Seeing the login page for a few seconds before it disappears is confusing for the user.

  Right now, I'm trying to avoid refreshing the page in Angular. This link is not about Angular.

  For instance, when changing the language in any abp project, the texts are replaced without the page needing to refresh. How is it done ?

  The link you provided is for implementing passwordless authentication with MVC when I'm trying to figure out how to refresh the page without reloading (after autologin) in Angular.

  Hello,

  I apologies for your inconvenience, yes that link is for MVC. Angular uses oAuth2 as an authentication method.

  To refresh the page without reloading (after autologin) in Angular try to add below code in app.comonent.ts

  export class AppComponent {
    constructor(private authService:AuthService, private router:Router)   { }
     
     ngOnInit(): void {
      
      if (this.authService.isAuthenticated) {
        this.router.navigate(this.router.getCurrentNavigation().extras.state?.redirect || ['/']);
      }
      else {
        this.router.navigate(['/']);
      }
   }
  }
  

  Thanks

  I was still getting the error so I tried another approach : replace the ToolbarComponent with my own, like explained here. In my custom toolbar, I can now check if the user is public or not and show the corresponding menu accordingly.

  However, I get another console error :

  ERROR Error: NG0100: ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'null'. Current value: 'undefined'. Expression location: MyToolbarContainerComponent component. Find more at https://angular.io/errors/NG0100

      at refreshView (core.mjs:12898:13)
      at detectChangesInView (core.mjs:13062:9)
  

  The problem seems to be here :

       <lpx-toolbar [profileRef]="profileRef$" (profileClick)="toggleCtxMenu()">
      <ng-container
  --->    ngIf="{
              user: userProfileService.user$ | async,
              profileRef: profileRef$ | async
          } as data"
      >
          <lpx-context-menu *ngIf="data.profileRef" #menu="lpx-context-menu" (lpxClickOutside)="menu.close()" [exceptedRefs]="[data.profileRef]">
              <lpx-context-menu-header>
                  <div class="lpx-user-ctx-header">
                      <div class="lpx-user-ctx-img">
                          <lpx-avatar [avatar]="data.user?.avatar"></lpx-avatar>
                      </div>
                      <div class="lpx-user-ctx-info">
                          <span class="lpx-context-menu-user-name">
                              {{ data.user?.fullName || data.user?.userName }}
                          </span>
                          <span *ngIf="data.user?.tenant?.name as tenantName" class="lpx-context-menu-user-tenant">
                              {{ tenantName }}
                          </span>
                          <span class="lpx-context-menu-user-email">{{ data.user?.email }}</span>
                      </div>
                  </div>
              </lpx-context-menu-header>
              <ng-container *ngFor="let actions of data.user?.userActionGroups">
                  <lpx-context-menu-action-group>
                      <lpx-navbar-routes [navbarItems]="actions" [routerItem]="false"></lpx-navbar-routes>
                  </lpx-context-menu-action-group>
              </ng-container>
          </lpx-context-menu>
      </ng-container>
  </lpx-toolbar>
  

  I downloaded lepton-x source code for comparison but there seems to be no difference between my html and yours.
