Remove or block sign in top menu option in Adobe Reader 64bit

Is there any way to remove the sign in option on the top menu bar in Adobe Reader x64 or prevent users from logging in?

I have tried all the usual reg keys but there appears to be no way to suppress or block this menu item.

Whilst i have disabled the online services i would like to be able to go further and prevent users from even logging into an account via Adobe Reader.

Hi Anand, we are using the Continuous track, we have no issue with the 32bit reader install but when using the x64 unified installer there appears to be no setting or configuration that completely removes the ability for users to create and sign into an Adobe Account.

We have used options such as bUpdater and bToggleAdobeDocumentServices but these still allow users to login.

Due to the industry we are in we cannot have the risk of any data leakage and we have no requirement for users to have an Adobe account.

Thanks

Hello @jonathans62717764

Please note that For the 64-bit unified installer, Adobe documents sign-in as part of how the app determines Acrobat vs Reader capability: users with Acrobat rights get Acrobat features after sign-in, and signed-out users get Reader behavior when reduced/read-only mode is enforced. Check these articles for more details: https://www.adobe.com/devnet-docs/acrobatetk/tools/DesktopDeployment/singleinstaller.html

What to check

For Reader-only behavior on the 64-bit unified installer, make sure the unified-app key is applied here:
1. HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown
  
  "bIsSCReducedModeEnforcedEx"=dword:00000001
This key for running unified Acrobat in Reader/read-only mode without requiring users to sign in.

2. https://www.adobe.com/devnet-docs/acrobatetk/tools/DesktopDeployment/singleinstaller.html’
Please Do not rely on bToggleAdobeDocumentServices alone. Adobe documents that it disables Document Cloud service access, but it does not cover every service, and Adobe states that to disable all services you should use the services bUpdater key.

Use the services key, not the product-update key:

HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\cServices

"bUpdater"=dword:00000000

this disables all Adobe services, including the sign-in screen, and that it is not the same as FeatureLockDown\bUpdater, which disables product updates.

To remove the Help > Sign In / Sign Out UI item, also set:

HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown

"bSuppressSignOut"=dword:00000001

For account creation with your organization’s domain, the supported enterprise control is Domain Enforcement in the Adobe Admin Console. Adobe documents that Domain Enforcement restricts organization-owned domains to prevent users from creating and using personal Adobe ID accounts with those domains. If you need centrally managed accounts only, Adobe documents Enterprise ID as organization-created, owned, and managed, and users cannot create an Enterprise ID or sign up directly with one.

Check these articles for more details:

https://helpx.adobe.com/business/enterprise/identity-sso/set-up-identity/set-up-identity-without-sso.html

I hope this helps, and if the issue still continues, and you have active Enterprise license, I will request to contact the Enterprise support team through admin console section, so that the dedicated team can assist you.

Anand Sri.

As far as I know, there isn't an official setting or registry key that completely removes or hides the Sign In option in Adobe Reader 64-bit.

If you've already disabled Adobe's online services, you've done most of what's officially supported. If you need to completely prevent users from signing in, you'd likely have to enforce it through your organization's policies, such as AppLocker, Group Policy, or network restrictions, rather than through Adobe Reader itself.

Hello @jonathans62717764,

I hope you are doing well, and thanks for reaching out. We're sorry for the trouble you had.

Could you please share more details about the issue/workflow?

Is the environment using Adobe Acrobat Reader (Continuous track) or a Classic/Enterprise-managed deployment?

Is the goal to prevent sign-in for all users in a managed enterprise environment (e.g., via GPO/registry/plist), or for individual unmanaged installations?

Have you tried the suggestions from the EK document on suppressing the Sign in? If not, please refer to this article, and try the suggestions: https://adobe.ly/4q1Yn5K

You need the Adobe Acrobat Customisation Wizard to make changes: https://adobe.ly/4w74WoS

For all the locable settings and preferences, please refer to this article: https://adobe.ly/4xkKnX8

Let us know how it goes, and share your observations. Please reach out if you need any assistance.

Regards,

Anand Sri.
