 ### Removed
 
+- Removed `-LaunchBrowser`, `-NoPopup` and credential based auth on `Register-PnPEntraIDApp` and `Register-PnPEntraIDAppForInteractiveLogin` cmdlets. The default auth method is now Interactive.
 - Removed `-LaunchBrowser` option on `Connect-PnPOnline` for interactive logins and device logins as it is default now and the popup based authentication window has been removed.
 - Removed `-UseWebLogin` option on `Connect-PnPOnline`. It used a very old, questionable approach to authentication. Use `-Interactive` or if you require an ACS connection `-ClientId` and `-ClientSecret`
 - Removed `Invoke-PnPTransformation` cmdlet as it was never supported.

 | Connect-PnPOnline | Removed `-UseWebLogin` on `Connect-PnPOnline`. It used a very outdated and questionable (reusing an auth cookie) authentication method which implementation broke easily. If you require an ACS connection for certain functionality, consider using `-ClientId` in combination with `-ClientSecret` instead. |
 | Connect-PnPOnline | Removed `-LaunchBrowser` option for Interactive login flows. It is the default now and removed the popup based authentication option |
 | Connect-PnPOnline | Removed `-LaunchBrowser` option for Device Login flows. It is the default now. |
