Your guests do not need to create a separate account to access the Guest Dashboard.
When a guest completes a booking through your HomeRunner website checkout, a Guest Dashboard account is created automatically at that moment, using the email address the guest entered at checkout. The PMS reservation and the website account are already linked to the same booking.
If the guest has not set a password yet. The guest can go straight to the Guest Dashboard lost-password page and request a reset using the booking email.
