then you won't be able to update the app. All apps are tied to the apple id that was used to purchase/download it.

You can delete the app and install it with your new apple id.

Did you ever know it??

Those apps were purchased with that old ID and aren't updatable with out the password. Your only option is to delete those apps and re-purchase/download them under your new App Store account ID. You can't transfer ownership to you new ID and you'll have to pay again...

I suspect it is because the apps you have on your iPhone were downloaded from the previous account and now have updates available. In order to update, the iPhone need to sign into the App Store with the older account. If that is the case since you no longer have the password I have found no fix for it other than to add the older account to the Family Share, however in your case, you may need to remove the apps and reinstall them under the new account.

Alternatively, you have services that are still "using" the former ID such as the message app or FaceTime etc in that case, sign in with the new account. Good luck finding the cause.
