+The guidance in this article relies upon either creating the app with **Individual Accounts** for the new app's **Authentication type** or [scaffolding Identity into an existing app](xref:security/authentication/scaffold-identity#scaffold-identity-into-a-blazor-project).

-## Scaffold the Enable Authenticator component into the app
-
-Follow the guidance in <xref:security/authentication/scaffold-identity#scaffold-identity-into-a-blazor-project> to scaffold `Pages\Manage\EnableAuthenticator` into the app.

-> [!NOTE]
-> Although only the `EnableAuthenticator` component is selected for scaffolding in this example, scaffolding currently adds all of the Identity components to the app. Additionally, exceptions may be thrown during the process of scaffolding into the app. If exceptions occur when database migrations occur, stop the app and restart the app on each exception. For more information, see [Scaffolding exceptions for Blazor Web App (`dotnet/Scaffolding` #2694)](https://github.com/dotnet/Scaffolding/issues/2694).
-
-Be patient while migrations are executed. Depending on the speed of the system, it can take up to a minute or two for database migrations to finish.

 ## Adding QR codes to the 2FA configuration page
 
 A QR code generated by the app to set up 2FA with an TOTP authenticator app must be generated by a QR code library.
