How to Fix Acrobat Reader Sign-In Issues on iPhone
Question details
The user is unable to log into the Acrobat Reader mobile app using their desktop credentials, preventing access to synchronized files.

- Product
- Adobe Acrobat Reader
- Device & OS
- iPhone (iOS)
- Scenario
- Attempting to access cloud-synced PDF files on an iPhone using the same account credentials that work successfully on a Windows desktop.
- Observed behavior
- The mobile application rejects the login credentials or fails to sign in, despite the exact same credentials working perfectly on the desktop version.
Ensure your iPhone has a stable internet connection and that you are not using an outdated auto-fill password saved in your iOS keychain.
Verify Your Credentials via the Web Browser
Testing your login on the official website helps determine if the issue is with your account configuration or the mobile app itself.
Authentication servers sometimes experience synchronization delays, or mobile apps might cache outdated login states. By logging in through a browser, you bypass the app's local cache to verify your account's true status.
Launch Safari or another web browser on your iPhone.
Go to the official Adobe Account website (account.adobe.com).
Type in the exact email address and password you use for the Windows desktop application.
If the web login fails, use the 'Forgot Password' link to reset your credentials. If the web login succeeds, the issue lies within the mobile app.

Update or Reinstall the Mobile App
Outdated application versions or corrupted cache data can cause persistent sign-in loops or authentication failures.
View, Edit, and Sync PDFs Seamlessly with WPS Office
If persistent mobile login errors are disrupting your workflow, WPS Office offers a robust, hassle-free alternative. Enjoy seamless cloud synchronization across your iPhone, Windows PC, and Mac without complicated authentication loops.
- 1. Download WPS Office: Install WPS Office from the App Store on your iPhone and download the desktop version from the official WPS website.
- 2. Sign in to your account: Use a single WPS account (via Google, Apple, or email) to log in on both your mobile device and your PC.
- 3. Sync your files: Open any PDF or document and save it to WPS Cloud to access it instantly from any of your connected devices.

Frequently Asked Questions
Why does my password work on my computer but not on my mobile app?
This discrepancy can happen due to mobile network restrictions, an outdated app version, or your iPhone's auto-fill feature inserting an old, previously saved password without your knowledge.
Will reinstalling the mobile app delete my local PDF files?
Yes, uninstalling the app may permanently remove files saved directly in the app's local storage. You should save or move any local, unsynchronized files to your iPhone's native 'Files' app before deleting the software.
How can I force the mobile app to sync with my desktop files once I am logged in?
Once successfully logged in, navigate to the 'Files' or 'Cloud' tab within the app and swipe down on the screen to manually refresh the list. Ensure both devices have active internet connections.
