How to Fix Acrobat Plugin Requesting Keychain Access on Mac
Question details
Users are encountering a recurring pop-up message stating that an Acrobat or Safari plugin wants to access confidential information stored in the macOS Keychain under v4.services.acrobat.com.

- Product
- Adobe Acrobat Plugin
- Device & OS
- macOS
- Scenario
- Opening Safari, browsing the web, or attempting to open and interact with PDF documents requiring cloud authentication.
- Observed behavior
- A macOS Keychain prompt appears requesting access to v4.services.acrobat.com. For many users, the pop-up loops continuously and reappears whether they select 'Allow', 'Always Allow', or 'Deny'.
Ensure you have your Mac administrator password ready, as modifying Keychain settings requires system-level authorization.
Delete the Problematic Adobe Keychain Entry
Removing the corrupted authentication token forces the Acrobat plugin to generate a fresh, error-free request, which usually stops the looping pop-up.
The v4.services.acrobat.com keychain entry is used by Adobe Document Cloud to verify your subscription and sync files. When this token becomes corrupted or out of sync with Safari, it triggers a continuous permission loop. Deleting it allows a clean reset.
Press Command + Space on your Mac keyboard to open Spotlight Search, type 'Keychain Access', and press Return.
In the search bar at the top right of the Keychain Access window, type 'v4.services.acrobat.com' or simply 'Acrobat'.
Right-click (or Control-click) the associated Adobe entry in the list and select 'Delete'. Enter your Mac administrator password if prompted to confirm the deletion.
Restart your Mac. Open Adobe Acrobat and sign into your Adobe account again. Select 'Always Allow' when the new Keychain prompt appears.
Update Adobe Acrobat and Safari
Updating both applications resolves compatibility bugs that can cause the plugin authentication prompt to loop.
Read and Edit PDFs Securely with WPS Office

Frequently Asked Questions
Why does v4.services.acrobat.com need access to my Mac Keychain?
This domain is used by Adobe Acrobat to securely store and retrieve your Adobe Document Cloud authentication tokens. The plugin requests access to verify your active subscription status and synchronize your cloud-stored PDFs.
Is it safe to click 'Always Allow' on the Acrobat Keychain prompt?
Yes. If you installed Acrobat or Adobe Reader from the official Adobe website, this is a legitimate macOS security request. Clicking 'Always Allow' should grant permanent permission, though caching bugs can occasionally cause the prompt to reappear.
How can I prevent PDF applications from forcing cloud storage?
If you want to avoid cloud-syncing issues, you can disable cloud-saving in Acrobat by going to Preferences > General and unchecking 'Show online storage when saving files.' Alternatively, use offline-focused software like WPS Office to handle PDFs locally.
Will removing the Acrobat Keychain entry delete my downloaded PDF documents?
No. The macOS Keychain only stores passwords, security certificates, and login tokens. Deleting the Acrobat entry simply forces the app to ask for your Adobe login credentials again; your files remain completely untouched.
