FluentCRM Smart Links & MemberPress

Hey everyone. I have several questions about these two together and I would appreciate your input.

If I choose to disable password fields on MemberPress memberships, it will send users an email and link for them to set up passwords later.

I have an automation that sends an email a few days before the membership event that gives a Smart Link so the user doesn't have to remember their password.

If they never finish setting up their account, does their account even exist? Will the Smart Link not work because they never set their own password?
