If a second administrator did not receive the welcome email for B2B Commerce, they can still access the store without changing the setup byLogging in from the Contact page in the Commerce app (C). This method allows administrators with existing Salesforce credentials to access the B2B Commerce environment directly through the Commerce app, bypassing the need for a welcome email. Additionally,Resetting the user ' s passwordfrom Setup and having the user login again (E)is a common workaround for access issues. This approach ensures that the user can reset their password and gain access to the store without relying on the initial welcome email. Checking Debug Logs (A), Enabling Guest Access in Experience Builder (B), and Logging in using the link in the More Information section of the Store page (D) are not standard practices for this particular scenario.
