Reset to default 2

The BrowserModule should be imported once within the AppModule. You don't need to import it again in a child module, and should be referenced like

import { BrowserModule } from '@angular/platform-browser';

Also, the ngClass directive forms part of the CommonModule, which does not seem to be imported in your AuthAdminModule 

@NgModule({
  imports: [
    ...
    CommonModule
  ],
  declarations: [ ... ] 
})
export class AuthAdminModule { }

You have wrongly imported BrowserModule in your auth-admin.module.ts

import { BrowserModule } from '@angular/platform-browser';

Further, for feature modules, you can import CommonModule module instead. BrowserModule is only required in the app.module.ts.

import { CommonModule } from '@angular/mon';
@NgModule({
  declarations: [
    ...
  ],
  imports: [
    CommonModule,
    ...
  ]
})
export class AuthAdminModule {}
