Hi

I have a project published in AppStore working fine, the project was migrated from StP to DnD so in order to develop some improvements i cloned the project and did all changes in the newly created one.

Now the issue comes when publishing the new project, as i use the same identifiers, certificates etc as the original one but im getting the following error : Your Apple ID username/app-specific password is invalid.

Is it that each thunkable project is a different app when it comes to publishing? Shouldnt that be independent if im using the same information when it comes to publishing?

The Apple ID and app-specific password are independent of anything you’d do in Thunkable. In general, it is best to have just one app specific password for all of your Thunkable projects.

Did you recently change your password for your Apple developer account? If yes, when you changed your password, Apple deleted your app-specific password. You need to follow the instructions [here](https://docs.thunkable.com/publishing-apps/publish-to-app-store-ios#app-specific-password) to create a new one!

Thanks @matt_conroy , this is exactly what happended. I changed Apple password so the app-specific password was deleted.

Thanks!
