Salesforce Grant Login Access for Third-Party Support Not Available

The following steps resolve the issue of third-party support not appearing in the Grant Account Login Access list.

Step 1: Enable Login Access Policy

1. Navigate to Setup > Security > Login Access Policies.
2. Confirm that login access for the third-party support provider is selected for all users.

Step 2: Assign the Third-Party License to Users

You must assign the third-party package license to yourself or your users to make the third-party support option appear under the "Grant Access To" section.

1. From Setup, enter Installed Packages in the Quick Find box, then select Installed Packages.
2. Click Manage Licenses next to the package.
3. Click Add Users.
4. Select the users:
   1. To select individual users, use the checkboxes. When the list includes all users, click Add.
   2. To select all users for the current view, click Add All Users, then click OK.

Note: To assign licenses for a package, you must have access to the package and at least one available license.
Once both steps are completed, the third-party support provider appears in the Grant Account Login Access list.
