Registration Page fields

Hello!
Is it possibile a multistep registration as: profilepress.net/demos/multi-step-registration-form-wordpress/
It is also possible to ask only email and password and no username?

Thank you

Step by Step registration can be enabled within CB > Configuration > Registration. Review the CB Primer Book or the videos below for further details.

Yes, set the username field to not display on registration within CB > Field Management. You can set what the username is set to, as it won't be available to supply, within CB > Configuration > User Profile using the Username Fallback parameter.

Thank you very much!

Now i need to redirect user to his profile after registration and at the same time send the confirmation email..

What is wrong with CB autoaction?

Use the onAfterSaveUserRegistration trigger which is fired after frontend registration is completed successfully (all operations). Your redirect should be non-SEF and begin with index.php.
