How to Make Lightning Experience the Only Experience for Some Users

 Ready for some of your users to go all-in on Lightning Experience? Keep them in the new interface by removing the option to switch back to Salesforce Classic.

When you enable Lightning Experience, users with the Lightning Experience User permission automatically get the Switcher. The Switcher lets users move back and forth between the new and classic Salesforce interfaces. But you can remove the Switcher for designated users.

From Setup, create a permission set that includes the Hide Option to Switch to Salesforce Classic permission then assign the permission set to the desired users. Or, enable the permission in a custom profile to remove the Switcher from everyone in that profile.

Users see Lightning Experience the next time they log in to Salesforce. They no longer see the Switch to Salesforce Classic link.

Even if the Hide Option to Switch to Salesforce Classic permission set is assigned, admins with the Customize Application or Modify All Data user permission can use the Switcher to get to Salesforce Classic.
