Protect Experience Cloud Users by Verifying Email Address Changes
To protect user accounts against security threats, Salesforce now
automatically enables the Require email confirmations for email address changes setting. With
this setting enabled, Experience Cloud site users must verify their email address
changes.
Where: This change applies to Aura, LWR, and Visualforce sites accessed through Lightning Experience and Salesforce Classic in Enterprise, Essentials, Unlimited, and Developer editions.
