Path: Configuration > Lead > Forced Conversion
If a Lead is filling out a contact form or modal on the website, this setting will log that action in the Lead's Detail Page, but not require them to log in.
Please note: A password will still be required if anyone tries to take any of the following actions: favorite a property, saving a search, adding a property note or logging in via a modal.
This will allow the leads already entered in your database to bypass the requirement of a password, allowing for simpler user experience.
To set this up...
1.) Go to Settings
2.) Go to Configuration > Lead
3.) Click on "Forced Conversion" at the top.
4.) Check the box to "Allow Logged Out Leads to Post Contact/Inquiry/Showing/Email-A-Friend forms without having to Log In.
