Follow these steps if you want to send a set password link to your contact:
1. When creating a new contact:
While adding a new contact, check the field Send SET Password Link and do not fill in the password field.
After the contact is created, an email with the set password link will be sent.
2. When the contact is already created:
Check the field Send SET Password Link and click Save. An email will be sent to the contact.
This link will expire after 48 hours.
You need to have configured email SMTP to use this feature.
