Hi @akanitony,
Just a heads up, if you’ve purchased a LifterLMS add-on or subscription via LifterLMS.com you should not post here. Instead, open a new support request from your LifterLMS.com account dashboard.
A member of the support team will get in touch with you as soon as possible.
That said, at this time we do not have an email verification set in LifterLMS.
As an alternative you could go into your LifterLMS->Settings->Accounts and turn on the setting for Disable Usernames so LifterLMS creates the username for the student that they receive in the Student Welcome Email found under LifterLMS->Settings->Notifications.
I hope this helps!
Please let us know if you have any further questions!
Thanks and take care,
