Free edition email confirmation

Free edition email confirmation

Hello,

I'm looking to use ADSelfService Plus free version for a limited temp project with ~25 users who will need to auth against a temp AD environment. ADSS will be internal-only, not public. Users will not be on AD bound machines, so I just need the users to be able to be able to change or reset their own AD passwords via web portal with any password change/reset approval/confirmed via email. Is email confirmation considered a second factor and limited to only 10 users? If so, what kind of confirmation is there for password change/reset without MFA. I'm unclear on what exactly the limitations are for free edition.

Thanks
