Hi @fabs .
You can create users without a password when carrying out a bulk import into a database connection, they would then need to go through the password reset flow before they could login.

Please see the documentation here on a way you could implement an invite flow using our current feature set:
Using the above you re-purpose the reset password flow as a “choose your new account password”, and you can customise the Password Reset page so the text makes more sense in this context for your end-users.
