email verification step in Lock

Is there a way for the signup on the lock to force an email verification step? We don’t want the user to proceed into the app without verifying their email first. The passwordless lock has a nice mechanism for asking the user to check their email or resend the email. Is there a way to implement that with username/password login, or am I missing something?

You can enable the rule titled Force Email Verification via the Dashboard:

This rule will ensure that the user receives an Unauthorized error forcing them to verify their email before they can proceed.

I have more than one client, even though I enabled the Email Verification rule, the missing “email_verified” field coming for other clients. How do I enable the rule for the clients I want ?
