How to Update or Reinstall Adobe Acrobat on iPhone with a New Apple ID
Question details
The user needs to update or reinstall Adobe Acrobat Reader on an iPhone using a different Apple ID, without losing locally stored or synced PDF documents.

- Product
- Adobe Acrobat Reader
- Device & OS
- iPhone / iOS
- Scenario
- Attempting to update an incompatible version of Adobe Acrobat Reader after the original Apple ID used to download it has been permanently closed.
- Observed behavior
- The iOS App Store blocks the app update process by continuously prompting for the password of the old, closed Apple ID.
Ensure you have access to your Adobe account credentials and verify that your important PDF files are either synced to Adobe Document Cloud or manually backed up to iCloud Drive before deleting the app.
Backup Local Documents and Reinstall with Current Apple ID
Since iOS strictly links app downloads to the Apple ID used at the time of purchase, you must delete the existing app and reinstall it with your new Apple ID. Backing up data first prevents permanent loss of local files.
Apple does not allow apps downloaded with one Apple ID to be updated using another. To bypass the old Apple ID prompt, the app must be completely removed from your iOS device and downloaded fresh.
Because deleting an app also removes its locally isolated app data, it is crucial to relocate any PDFs stored solely on your device before proceeding.
Open the native 'Files' app on your iPhone, navigate to 'On My iPhone' > 'Acrobat', select all your PDF documents, and move or copy them to 'iCloud Drive' or another safe folder.
Open a web browser, log in to Adobe Document Cloud with your original Adobe account, and confirm that your synced files are visible and up to date.
Go to your iPhone Home Screen, long-press the Adobe Acrobat Reader icon, tap 'Remove App', and then select 'Delete App' to uninstall it entirely.
Open the App Store, tap your profile picture to ensure you are signed in with your current, active Apple ID, search for 'Adobe Acrobat Reader', and download it.
Launch the newly installed Acrobat Reader app, sign in using your original Adobe account credentials to sync your cloud files, and use the Files app to import any local PDFs you previously backed up.

Frequently Asked Questions
Why does the App Store ask for my old Apple ID password to update Adobe Acrobat?
iOS securely links every app installation to the Apple ID used at the time of the original download. If you switch to a new Apple ID, the App Store will still require the original account's credentials to authorize updates. To fix this, you must delete and reinstall the app under the new account.
Will my Adobe Document Cloud files be deleted if I uninstall the iPhone app?
No. Any files that have successfully synced to your Adobe Document Cloud are tied to your Adobe account, not the physical app on your iPhone. Once you reinstall the app and log back in with your Adobe credentials, your synced files will be restored.
How do I ensure my local PDFs are backed up before deleting the app?
You can use the built-in iOS Files app. Navigate to 'Browse', select 'On My iPhone', and open the 'Acrobat' folder. Select the files you wish to keep, tap the folder icon at the bottom, and copy them to an external location like iCloud Drive.
