Solution 1Recommended

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Authentication servers sometimes experience synchronization delays, or mobile apps might cache outdated login states.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.

1
Open your mobile browser

Launch Safari or another web browser on your iPhone.

2
Navigate to the account page

Go to the official Adobe Account website (account.adobe.com).

3
Enter your credentials

Type in the exact email address and password you use for the Windows desktop application.

4
Evaluate the result

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.

Verify Your Credentials via the Web Browser
Record Error Messages: If the mobile app displays a specific error code or message during the failed login attempt, take a screenshot or write it down for further troubleshooting.

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This discrepancy can happen due to mobile network restrictions, an outdated app version, or your iPhone's auto-fill feature inserting an old, previously saved password without your knowledge.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.
