The Manage Customer User permission has been removed from all standard profiles to give
admins more control over who can manage customer users. You can still grant this access to users
who manage customer and partner users. To grant access on standard profiles, create a permission
set with the same access as the Manage Customer User permission and assign it to standard profiles
as needed. To grant access on custom profiles, either manually enable the Manage Customer User
permission or assign a perm set that grants the same permissions.
Where: This change applies to Lightning communities and Salesforce Tabs + Visualforce
communities, accessed through Lightning Experience and Salesforce Classic. Communities are
available in Enterprise, Performance, Unlimited, and Developer editions.
Who: The Manage Customer User permission is available only to Customer Community,
Partner Community, and Customer Community Plus users.
