Hi @Suvi Anju
It is by default the web app will only be accessible to you. To add authentication for example, restrict access to the app to members of your Azure tenant.
Please find below steps:
- Go to the Azure portal and search for the app name you specified during publishing. Select the web app, and go to the Authentication tab on the left navigation menu. Then select Add an identity provider.
- Select Microsoft as the identity provider. The default settings on this page will restrict the app to your tenant only, so you don't need to change anything else here. Then select Add.
Now users will be asked to sign in with their Azure Active Directory account to be able to access your app. You can follow a similar process to add another identity provider if you prefer. The app doesn't use the user's login information in any other way other than verifying they are a member of your tenant.

Hope the answer is useful to you and thanks for the great question.
