An identity architect is implementing a mobile-first Consumer Identity Access Management (CIAM) for external users.

External Identity Licenses are required to enable external users to access Salesforceresources via a CIAM solution. Email Verification Credits and SMS Verification Credits are required to enable email or mobile phone number verification for user authentication. Identity Connect Licenses are not required for this scenario, as Identity Connect is a tool for synchronizing user data between Salesforce and Active Directory.
