How to make registration in WordPress invite-only?

Question

User identification

Hello.
I want to make registration in WordPress only by invites, sort of like in the Leprosarium.
So that each user is given a certain number of invites, and that you can flexibly configure the policy for issuing them.
Tell me how best to implement this without writing in PHP?

Hello!
Have you tried looking for plugins? Wordpress invites, wordpress invitation , wordpress registration by invitation
1) https://wordpress.org/plugins/invitation-based-reg...
2) https://ru.wordpress.org/plugins/wp-invites/
3) https://wordpress.org/plugins/baw-invitation-codes/
4) https://wordpress.org/plugins/cm-invitation-codes/
5) https://wordpress.org/plugins/wp-members/
And if the functionality of these plugins is not enough, then you can look for premium plugins on codecanyon. Well, or write yourself in PHP.
