Manage External Community Users in Lightning Experience
No more switching between Lightning Experience and Salesforce Classic
to manage external community members. From within Lightning Experience, you can create
and disable partner and customer accounts and users and log in as a community
user.
Good news! All actions that you can take on a person account in Salesforce Classic are available in Lightning Experience.
And the fun doesn’t stop there. All login actions that are available in Salesforce Classic can also be performed in Lightning Experience.
