Email Verification After Successful Registration

Good day,

Is there a way of letting users register FIRST and start to use the site and the later on have the option of verifying their emails or not.

Yes, you can require email verification or disable it in HivePress/Settings/Users/Registration, but if you mean allowing to use the site with some restrictions until the email is verified there’s no such option at the moment (if the email verification is enabled, it’s required for the initial login).
